This guide is part 2 of a series.
|
||||||
|
|
||||||
|
[**Part 1**]({{<ref "provider-alibabacloud" >}}) covers
|
||||||
|
installing Crossplane and connecting your Kubernetes cluster to Alibaba Cloud.
|
||||||
|
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
This guide walks you through building and accessing a custom API with Crossplane.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
* Complete [quickstart part 1]({{<ref "provider-alibabacloud" >}}) connecting Kubernetes
|
||||||
|
to Alibaba Cloud.
|
||||||
|
* an Alibaba Cloud account with permissions to create an ECS instance, VPC, VSwitch and SecurityGroup.
|
||||||
|
|
||||||
|
{{<expand "Skip part 1 and just get started" >}}
|
||||||
|
|
||||||
|
1. Add the Crossplane Helm repository and install Crossplane
|
||||||
|
|
||||||
|
```shell
|
||||||
|
helm repo add \
|
||||||
|
crossplane-stable https://charts.crossplane.io/stable
|
||||||
|
helm repo update
|
||||||
|
|
||||||
|
helm install crossplane \
|
||||||
|
crossplane-stable/crossplane \
|
||||||
|
--namespace crossplane-system \
|
||||||
|
--create-namespace
|
||||||
|
```
|
||||||
|
|
||||||
|
2. When the Crossplane pods finish installing and are ready, apply the Alibaba Cloud Provider
|
||||||
|
|
||||||
|
```yaml {label="provider",copy-lines="all"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: pkg.crossplane.io/v1
|
||||||
|
kind: Provider
|
||||||
|
metadata:
|
||||||
|
name: provider-upjet-alibabacloud
|
||||||
|
spec:
|
||||||
|
package: xpkg.upbound.io/crossplane-contrib/provider-upjet-alibabacloud:v0.2.0
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
|
||||||
|
3. Create a file with your Alibaba Cloud access keys
|
||||||
|
|
||||||
|
```yaml
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Secret
|
||||||
|
metadata:
|
||||||
|
name: alibabacloud-secret
|
||||||
|
namespace: crossplane-system
|
||||||
|
type: Opaque
|
||||||
|
stringData:
|
||||||
|
credentials: |
|
||||||
|
{
|
||||||
|
"access_key": $@<alibaba_cloud_access_key>$@,
|
||||||
|
"secret_key": $@<alibaba_cloud_secret_key>$@
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
4. Create a Kubernetes secret from the Alibaba Cloud keys
|
||||||
|
|
||||||
|
```shell
|
||||||
|
kubectl apply -f alibabacloud-credential.yaml
|
||||||
|
```
|
||||||
|
|
||||||
|
5. Create a ProviderConfig
|
||||||
|
|
||||||
|
```
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: alibabacloud.crossplane.io/v1beta1
|
||||||
|
kind: ProviderConfig
|
||||||
|
metadata:
|
||||||
|
name: default
|
||||||
|
spec:
|
||||||
|
credentials:
|
||||||
|
source: Secret
|
||||||
|
secretRef:
|
||||||
|
namespace: crossplane-system
|
||||||
|
name: alibabacloud-secret
|
||||||
|
key: credentials
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
{{</expand >}}
|
||||||
|
|
||||||
|
## Create a custom API
|
||||||
|
|
||||||
|
Crossplane allows you to build your own custom APIs for your users, abstracting
|
||||||
|
away details about the cloud provider and their resources. You can make your API
|
||||||
|
as complex or simple as you wish.
|
||||||
|
|
||||||
|
The custom API is a Kubernetes object.
|
||||||
|
Here is an example custom API.
|
||||||
|
|
||||||
|
```yaml {label="exAPI"}
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|
kind: VirtualMachine
|
||||||
|
metadata:
|
||||||
|
name: my-vm
|
||||||
|
spec:
|
||||||
|
location: "CN"
|
||||||
|
```
|
||||||
|
|
||||||
|
Like any Kubernetes object the API has a
|
||||||
|
{{}}version{{}},
|
||||||
|
{{}}kind{{}} and
|
||||||
|
{{}}spec{{}}.
|
||||||
|
|
||||||
|
## Define a group and version
|
||||||
|
|
||||||
|
To create your own API start by defining an
|
||||||
|
[API group](https://kubernetes.io/docs/reference/using-api/#api-groups) and
|
||||||
|
[version](https://kubernetes.io/docs/reference/using-api/#api-versioning).
|
||||||
|
|
||||||
|
The _group_ can be any value, but common convention is to map to a fully
|
||||||
|
qualified domain name.
|
||||||
|
|
||||||
|
<!-- vale gitlab.SentenceLength = NO -->
|
||||||
|
The version shows how mature or stable the API is and increments when changing,
|
||||||
|
adding or removing fields in the API.
|
||||||
|
<!-- vale gitlab.SentenceLength = YES -->
|
||||||
|
|
||||||
|
Crossplane doesn't require specific versions or a specific version naming
|
||||||
|
convention, but following
|
||||||
|
[Kubernetes API versioning guidelines](https://kubernetes.io/docs/reference/using-api/#api-versioning)
|
||||||
|
is strongly recommended.
|
||||||
|
|
||||||
|
* `v1alpha1` - A new API that may change at any time.
|
||||||
|
* `v1beta1` - An existing API that's considered stable. Breaking changes are
|
||||||
|
strongly discouraged.
|
||||||
|
* `v1` - A stable API that doesn't have breaking changes.
|
||||||
|
|
||||||
|
This guide uses the group
|
||||||
|
{{<hover label="version" line="1">}}compute.example.com{{</hover>}}.
|
||||||
|
|
||||||
|
Because this is the first version of the API, this guide uses the version
|
||||||
|
{{<hover label="version" line="1">}}v1alpha1{{</hover>}}.
|
||||||
|
|
||||||
|
```yaml {label="version",copy-lines="none"}
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|
```
|
||||||
|
|
||||||
|
## Define a kind
|
||||||
|
|
||||||
|
The API group is a logical collection of related APIs. In a group are
|
||||||
|
individual kinds representing different resources.
|
||||||
|
|
||||||
|
For example a `database` group may have a `Relational` and `NoSQL` kinds.
|
||||||
|
|
||||||
|
The `kind` can be anything, but it must be
|
||||||
|
[UpperCamelCased](https://kubernetes.io/docs/contribute/style/style-guide/#use-upper-camel-case-for-api-objects).
|
||||||
|
|
||||||
|
This API's kind is
|
||||||
|
{{<hover label="kind" line="2">}}NoSQL{{</hover>}}
|
||||||
|
|
||||||
|
```yaml {label="kind",copy-lines="none"}
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|
kind: VirtualMachine
|
||||||
|
```
|
||||||
|
|
||||||
|
## Define a spec
|
||||||
|
|
||||||
|
The most important part of an API is the schema. The schema defines the inputs
|
||||||
|
accepted from users.
|
||||||
|
|
||||||
|
This API allows users to provide a
|
||||||
|
{{<hover label="spec" line="4">}}location{{</hover>}} of where to run their
|
||||||
|
cloud resources.
|
||||||
|
|
||||||
|
All other resource settings can't be configurable by the users. This allows
|
||||||
|
Crossplane to enforce any policies and standards without worrying about
|
||||||
|
user errors.
|
||||||
|
|
||||||
|
```yaml {label="spec",copy-lines="none"}
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|
kind: VirtualMachine
|
||||||
|
spec:
|
||||||
|
location: "CN"
|
||||||
|
```
|
||||||
|
|
||||||
|
## Apply the API
|
||||||
|
|
||||||
|
Crossplane uses
|
||||||
|
{{<hover label="xrd" line="3">}}Composite Resource Definitions{{</hover>}}
|
||||||
|
(also called an `XRD`) to install your custom API in
|
||||||
|
Kubernetes.
|
||||||
|
|
||||||
|
The XRD {{<hover label="xrd" line="6">}}spec{{</hover>}} contains all the
|
||||||
|
information about the API including the
|
||||||
|
{{<hover label="xrd" line="7">}}group{{</hover>}},
|
||||||
|
{{<hover label="xrd" line="12">}}version{{</hover>}},
|
||||||
|
{{<hover label="xrd" line="9">}}kind{{</hover>}} and
|
||||||
|
{{<hover label="xrd" line="13">}}schema{{</hover>}}.
|
||||||
|
|
||||||
|
The XRD's {{<hover label="xrd" line="5">}}name{{</hover>}} must be the
|
||||||
|
combination of the {{<hover label="xrd" line="9">}}plural{{</hover>}} and
|
||||||
|
{{<hover label="xrd" line="7">}}group{{</hover>}}.
|
||||||
|
|
||||||
|
The {{<hover label="xrd" line="13">}}schema{{</hover>}} uses the
|
||||||
|
{{<hover label="xrd" line="14">}}OpenAPIv3{{</hover>}} specification to define
|
||||||
|
the API {{<hover label="xrd" line="17">}}spec{{</hover>}}.
|
||||||
|
|
||||||
|
The API defines a {{<hover label="xrd" line="20">}}location{{</hover>}} that
|
||||||
|
must be {{<hover label="xrd" line="22">}}oneOf{{</hover>}} either
|
||||||
|
{{<hover label="xrd" line="23">}}CN{{</hover>}} or
|
||||||
|
{{<hover label="xrd" line="24">}}US{{</hover>}}.
|
||||||
|
|
||||||
|
Apply this XRD to create the custom API in your Kubernetes cluster.
|
||||||
|
|
||||||
|
```yaml {label="xrd",copy-lines="all"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|

|
||||||

|

type: string
|

|
oneOf:
|
||||||

|
||||||
|
claimNames:
|
||||||
|
kind: VirtualMachineClaim
|
||||||
|
plural: virtualmachineclaims
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
Adding the {{<hover label="xrd" line="29">}}claimNames{{</hover>}} allows users
|
||||||
|
to access this API either at the cluster level with the
|
||||||
|
{{<hover label="xrd" line="9">}}VirtualMachine{{</hover>}} endpoint or in a namespace
|
||||||
|
with the
|
||||||
|
{{<hover label="xrd" line="30">}}VirtualMachineClaim{{</hover>}} endpoint.
|
||||||
|
|
||||||
|
The namespace scoped API is a Crossplane _Claim_.
|
||||||
|
|
||||||
|
{{<hint "tip" >}}
|
||||||
|
For more details on the fields and options of Composite Resource Definitions
|
||||||
|
read the
|
||||||
|
[XRD documentation]({{<ref "../concepts/composite-resource-definitions">}}).
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
View the installed XRD with `kubectl get xrd`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get xrd
|
||||||
|
NAME ESTABLISHED OFFERED AGE
|
||||||
|
virtualmachines.compute.example.com True True 7s
|
||||||
|
```
|
||||||
|
|
||||||
|
View the new custom API endpoints with `kubectl api-resources | grep VirtualMachine`
|
||||||
|
|
||||||
|
```shell
|
||||||
|
kubectl api-resources | grep nosql
|
||||||
|
```
|
||||||
|
|
||||||
|
## Create a deployment template
|
||||||
|
|
||||||
|
When users access the custom API Crossplane takes their inputs and combines them
|
||||||
|
with a template describing what infrastructure to deploy. Crossplane calls this
|
||||||
|
template a _Composition_.
|
||||||
|
|
||||||
|
The {{<hover label="comp" line="3">}}Composition{{</hover>}} defines all the
|
||||||
|
cloud resources to deploy.
|
||||||
|
Each entry in the template
|
||||||
|
is a full resource definitions, defining all the resource settings and metadata
|
||||||
|
like labels and annotations.
|
||||||
|
|
||||||
|
This template creates an Alibaba Cloud
|
||||||
|
{{<hover label="comp" line="11">}}ECSInstance{{</hover>}}
|
||||||
|
{{<hover label="comp" line="46">}}SecurityGroup{{</hover>}},
|
||||||
|
{{<hover label="comp" line="69">}}VSwitch{{</hover>}} and
|
||||||
|
{{<hover label="comp" line="90">}}VPC{{</hover>}}.
|
||||||
|
|
||||||
|
This Composition takes the user's
|
||||||
|
{{<hover label="comp" line="36">}}location{{</hover>}} input and uses it as the
|
||||||
|
{{<hover label="comp" line="37">}}location{{</hover>}} used in the individual
|
||||||
|
resource.
|
||||||
|
|
||||||
|
{{<hint "important" >}}
|
||||||
|
This Composition uses an array of resource templates. You can patch each
|
||||||
|
template with data copied from the custom API. Crossplane calls this a _Patch
|
||||||
|
and Transform_ Composition.
|
||||||
|
|
||||||
|
You don't have to use Patch and Transform. Crossplane supports a variety of
|
||||||
|
alternatives, including Go Templating and CUE. You can also write a function in
|
||||||
|
Go or Python to template your resources.
|
||||||
|
|
||||||
|
Read the [Composition documentation]({{<ref "../concepts/compositions">}}) for
|
||||||
|
more information on configuring Compositions and all the available options.
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
Apply this Composition to your cluster.
|
||||||

|
||||||

which custom APIs can use this template to create resources.
|

```
|

|
## Access the custom API
|
||||||
|
|
||||||
|
With the custom API (XRD) installed and associated to a resource template
|
||||||
|
(Composition) users can access the API to create resources.
|
||||||
|
|
||||||
|
Create a {{<hover label="xr" line="3">}}VirtualMachine{{</hover>}} object to
|
||||||
|
create the cloud resources.
|
||||||
|
|
||||||
|
```yaml {copy-lines="all",label="xr"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|

|
||||||
|
spec:
|

|
||||||
|
availabilityZone: "CN"
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
|
||||||
|
View the resource with `kubectl get VirtualMachine`.
|
||||||
|
|
||||||
|
{{< hint "note" >}}
|
||||||
|
It may take up to five minutes for the resources to provision.
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get VirtualMachine
|
||||||
|
NAME SYNCED READY COMPOSITION AGE
|
||||||
|
my-vm True True crossplane-quickstart-vm-with-network 2m30s
|
||||||
|
```
|
||||||
|
This object is a Crossplane _composite resource_ (also called an `XR`).
|
||||||
|
It's a
|
||||||
|
single object representing the collection of resources created from the
|
||||||
|
Composition template.
|
||||||
|
|
||||||
|
View the individual resources with `kubectl get managed`
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get managed
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|

|
||||||
|
```
|
||||||
|
|
||||||
|
Accessing the API created all five resources defined in the template and linked
|
||||||
|
them together.
|
||||||
|
|
||||||
|
Delete the resources with `kubectl delete VirtualMachine`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl delete VirtualMachine my-vm
|
||||||
|
virtualmachine.compute.example.com "my-vm" deleted
|
||||||
|
```
|
||||||
|
|
||||||
|
Verify Crossplane deleted the resources with `kubectl get managed`
|
||||||
|
|
||||||
|
{{<hint "note" >}}
|
||||||
|
It may take up to 5 minutes to delete the resources.
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get managed
|
||||||
|
No resources found
|
||||||
|
```
|
||||||
|
|
||||||
|
## Using the API with namespaces
|
||||||
|
|
||||||
|
Accessing the API `VirtualMachine` happens at the cluster scope.
|
||||||
|
Most organizations
|
||||||
|
isolate their users into namespaces.
|
||||||
|
|
||||||
|
A Crossplane _Claim_ is the custom API in a namespace.
|
||||||
|
|
||||||
|
Creating a _Claim_ is just like accessing the custom API endpoint, but with the
|
||||||
|
{{<hover label="claim" line="3">}}kind{{</hover>}}
|
||||||
|
from the custom API's `claimNames`.
|
||||||
|
|
||||||
|
Create a new namespace to test create a Claim in.
|
||||||
|
|
||||||
|
```shell
|
||||||
|
$ kubectl create namespace crossplane-test
|
||||||
|
```
|
||||||
|
|
||||||
|
Then create a Claim in the `crossplane-test` namespace.
|
||||||
|
|
||||||
|
```yaml {label="claim",copy-lines="all"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: compute.example.com/v1alpha1
|
||||||
|
kind: VirtualMachineClaim
|
||||||
|
metadata:
|
||||||
|
name: my-namespaced-vm
|
||||||
|
namespace: crossplane-test
|
||||||
|
spec:
|
||||||
|
location: "CN"
|
||||||
|
availabilityZone: "CN"
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
View the Claim with `kubectl get claim -n crossplane-test`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get claim -n crossplane-test
|
||||||
|
NAME SYNCED READY CONNECTION-SECRET AGE
|
||||||
|
my-namespaced-vm True True 100s
|
||||||
|
```
|
||||||
|
|
||||||
|
The Claim automatically creates a composite resource, which creates the managed
|
||||||
|
resources.
|
||||||
|
|
||||||
|
View the Crossplane created composite resource with `kubectl get composite`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl get composite
|
||||||
|
NAME SYNCED READY COMPOSITION AGE
|
||||||
|
my-namespaced-vm-pjt8c True True crossplane-quickstart-vm-with-network 114s
|
||||||
|
```
|
||||||
|
|
||||||
|
Again, view the managed resources with `kubectl get managed`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|
instance.ecs.alibabacloud.crossplane.io/instance True True i-8vbaj0******** 2m25s
|
||||||
|
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|
securitygroup.ecs.alibabacloud.crossplane.io/group True True sg-8vb4pghz******** 2m26s
|
||||||
|
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|
vpc.vpc.alibabacloud.crossplane.io/vpc True True vpc-8vb7gz92******* 2m28s
|
||||||
|
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|
vswitch.vpc.alibabacloud.crossplane.io/vswitch True True vsw-8vbo4dng2******* 2m28s
|
||||||
|
```
|
||||||
|
|
||||||
|
Deleting the Claim deletes all the Crossplane generated resources.
|
||||||
|
|
||||||
|
`kubectl delete claim -n crossplane-test my-namespaced-vm`
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
$ kubectl delete claim -n crossplane-test my-namespaced-vm
|
||||||
|
virtualmachineclaim.compute.example.com "my-namespaced-vm" deleted
|
||||||
|
```
|
||||||
|
|
||||||
|
{{<hint "note" >}}
|
||||||
|
It may take up to 5 minutes to delete the resources.
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
Verify Crossplane deleted the composite resource with `kubectl get composite`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
kubectl get composite
|
||||||
|
No resources found
|
||||||
|
```
|
||||||
|
|
||||||
|
Verify Crossplane deleted the managed resources with `kubectl get managed`.
|
||||||
|
|
||||||
|
```shell {copy-lines="1"}
|
||||||
|
kubectl get managed
|
||||||
|
No resources found
|
||||||
|
```
|
||||||
|
|
||||||
|

Connect Crossplane to Alibaba Cloud to create and manage cloud resources from Kubernetes
|
||||||
|
with
|
||||||
|
[provider-upjet-alibabacloud](https://github.com/crossplane-contrib/provider-upjet-alibabacloud).
|
||||||
|
|
||||||
|
This guide is in two parts:
|
||||||
|
* Part 1 walks through installing Crossplane, configuring the provider to
|
||||||
|
authenticate to Alibaba Cloud and creating a _Managed Resource_ in Alibaba Cloud directly from your
|
||||||
|
Kubernetes cluster. This shows Crossplane can communicate with Alibaba Cloud.
|
||||||
|
* [Part 2]({{< ref "provider-alibabacloud-part-2" >}}) shows how to build and access a
|
||||||
|
custom API with Crossplane.
|
||||||
|
|
||||||
|
## Prerequisites
|
||||||
|
|
||||||
|
This quickstart requires:
|
||||||
|
|
||||||
|
* a Kubernetes cluster with at least 2 GB of RAM
|
||||||
|
* permissions to create pods and secrets in the Kubernetes cluster
|
||||||
|
* [Helm](https://helm.sh/) version v3.2.0 or later
|
||||||
|
* an Alibaba Cloud account with permissions to create a VPC
|
||||||
|
* Alibaba Cloud [access keys](https://help.aliyun.com/document_detail/53045.html) (AccessKey ID and AccessKey Secret)

|
## Install the Alibaba Cloud provider
|
||||||
|
|
||||||
|
Install the Alibaba Cloud OSS provider into the Kubernetes cluster with a Kubernetes
|
||||||
|
configuration file.
|
||||||
|
|
||||||
|
```yaml {label="provider",copy-lines="all"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: pkg.crossplane.io/v1
|
||||||
|
kind: Provider
|
||||||
|
metadata:
|
||||||
|
name: provider-upjet-alibabacloud
|
||||||
|
spec:
|
||||||
|
package: xpkg.upbound.io/crossplane-contrib/provider-upjet-alibabacloud:v0.2.0
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
|
||||||
|
The Crossplane {{< hover label="provider" line="3" >}}Provider{{}}
|
||||||
|
installs the Kubernetes Custom Resource Definitions (CRDs) representing Alibaba Cloud
|
||||||
|
services. These CRDs allow you to create Alibaba Cloud resources directly inside
|
||||||
|
Kubernetes.
|
||||||
|
|
||||||
|
Verify the provider installed with `kubectl get providers`.
|
||||||
|
```shell {copy-lines="1",label="getProvider"}
|
||||||
|
$ kubectl get providers
|
||||||
|
NAME INSTALLED HEALTHY PACKAGE AGE
|
||||||
|
provider-upjet-alibabacloud True True xpkg.upbound.io/crossplane-contrib/provider-upjet-alibabacloud:v0.2.0 128m
|
||||||
|
```
|
||||||
|
You can view the new CRDs with `kubectl get crds`.
|
||||||
|
Every CRD maps to a unique Alibaba Cloud service Crossplane can provision and manage.
|
||||||
|
|
||||||
|
{{< hint type="tip" >}}
|
||||||
|
See details about all the supported CRDs in the
|
||||||
|
[provider examples](https://github.com/crossplane-contrib/provider-upjet-alibabacloud/tree/main/examples).
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
## Create a Kubernetes secret for Alibaba Cloud
|
||||||
|
The provider requires credentials to create and manage Alibaba Cloud resources.
|
||||||
|
Providers use a Kubernetes Secret to connect the credentials to the provider.
|
||||||
|
|
||||||
|
Generate a Kubernetes Secret from your Alibaba Cloud access keys and
|
||||||
|
then configure the Provider to use it.
|
||||||
|
|
||||||
|
### Generate an Alibaba Cloud credential
|
||||||
|
For basic user authentication, use an Alibaba Cloud access keys file.
|
||||||
|
|
||||||
|
{{< hint type="tip" >}}
|
||||||
|
The [Alibaba Cloud documentation](https://www.alibabacloud.com/help/en/ram/user-guide/create-an-accesskey-pair)
|
||||||
|
provides information on how to generate Alibaba Cloud access keys.
|
||||||
|
{{< /hint >}}
|
||||||
|
|
||||||
|
Create a `Secret` object named
|
||||||
|
{{< hover label="kube-create-secret" line="2">}}alibabacloud-secret{{< /hover >}}
|
||||||
|
in the {{< hover label="kube-create-secret" line="3">}}crossplane-system{{</ hover >}} namespace
|
||||||
|
with the `stringData` containing the Alibaba Cloud accessKeyId and accessKeySecret.
|
||||||
|
|
||||||
|
{{< editCode >}}
|
||||||
|
```yaml {label="configSecret",copy-lines="all"}
|
||||||
|
apiVersion: v1
|
||||||
|
kind: Secret
|
||||||
|
metadata:
|
||||||
|
name: alibabacloud-secret
|
||||||
|
namespace: crossplane-system
|
||||||
|
type: Opaque
|
||||||
|
stringData:
|
||||||
|
credentials: |
|
||||||
|
{
|
||||||
|
"access_key": $@<alibaba_cloud_access_key>$@,
|
||||||
|
"secret_key": $@<alibaba_cloud_secret_key>$@
|
||||||
|
}
|
||||||
|
```
|
||||||
|
{{< /editCode >}}
|
||||||
|
Save this text file as `alibabacloud-credential.yaml`.
|
||||||
|
|
||||||
|
## Create a Kubernetes secret with the Alibaba Cloud credentials
|
||||||
|
|
||||||
|
Apply the secret file to generate the secret object.
|
||||||
|
```shell {label="kube-create-secret",copy-lines="all"}
|
||||||
|
kubectl apply -f alibabacloud-credential.yaml
|
||||||
|
```
|
||||||
|
Verify the secret was created with `kubectl describe secrets`.
|
||||||
|
{{< hint type="note" >}}
|
||||||
|
The size may be larger if there are extra blank spaces in your text file.
|
||||||
|
{{< /hint >}}
|
||||||
|
```shell {copy-lines="1",label="getSecret"}
|
||||||
|
$ kubectl describe secret alibabacloud-secret -n crossplane-system
|
||||||
|
Name: alibabacloud-secret
|
||||||
|
Namespace: crossplane-system
|
||||||
|
Labels: <none>
|
||||||
|
Annotations: <none>
|
||||||
|
|
||||||
|
Type: Opaque
|
||||||
|
|
||||||
|
Data
|
||||||
|
====
|
||||||
|
credentials: 97 bytes
|
||||||
|
```
|
||||||
|
## Create a ProviderConfig
|
||||||
|
A {{< hover label="providerconfig" line="3">}}ProviderConfig{{</ hover >}}
|
||||||
|
customizes the settings of the Alibaba Cloud Provider.
|
||||||
|
|
||||||
|
Apply the
|
||||||
|
{{< hover label="providerconfig" line="3">}}ProviderConfig{{</ hover >}}
|
||||||
|
with this Kubernetes configuration file:
|
||||||
|
```yaml {label="providerconfig",copy-lines="all"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: alibabacloud.crossplane.io/v1beta1
|
||||||
|
kind: ProviderConfig
|
||||||
|
metadata:
|
||||||
|
name: default
|
||||||
|
spec:
|
||||||
|
credentials:
|
||||||
|
source: Secret
|
||||||
|
secretRef:
|
||||||
|
namespace: crossplane-system
|
||||||
|
name: alibabacloud-secret
|
||||||
|
key: credentials
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
This attaches the Alibaba Cloud credentials, saved as a Kubernetes secret, as a
|
||||||
|
{{< hover label="providerconfig" line="9">}}secretRef{{</ hover>}}.

|
The
|
||||||
|
{{< hover label="providerconfig" line="11">}}spec.credentials.secretRef.name{{< /hover >}}
|
||||||
|
value is the name of the Kubernetes secret containing the Alibaba Cloud credentials in the

{{< hover label="providerconfig" line="10">}}spec.credentials.secretRef.namespace{{< /hover >}}.
|

## Create a managed resource
|
||||||
|
A _managed resource_ is anything Crossplane creates and manages outside of the Kubernetes cluster.
|
||||||
|
|
||||||
|
This guide creates an Alibaba Cloud VPC with Crossplane.
|
||||||
|
|
||||||
|
The VPC is a _managed resource_.
|
||||||
|
|
||||||
|
```yaml {label="xr"}
|
||||||
|
cat <<EOF | kubectl apply -f -
|
||||||
|
apiVersion: vpc.alibabacloud.crossplane.io/v1alpha1
|
||||||
|
kind: VPC
|
||||||
|
metadata:
|
||||||
|
name: crossplane-vpc
|
||||||
|
spec:
|
||||||
|
forProvider:
|
||||||
|
region: cn-zhangjiakou
|
||||||
|
cidrBlock: 10.0.0.0/8
|
||||||
|
description: test
|
||||||
|
enableIpv6: true
|
||||||
|
ipv6Isp: BGP
|
||||||
|
vpcName: crossplane-quickstart-vpc
|
||||||
|
EOF
|
||||||
|
```
|
||||||
|
The {{< hover label="xr" line="2">}}apiVersion{{< /hover >}} and
|
||||||
|
{{< hover label="xr" line="3">}}kind{{}} are from the provider's CRDs.
|
||||||
|
|
||||||
|
The {{< hover label="xr" line="8">}}spec.forProvider.region{{< /hover >}} tells
|
||||||
|
Alibaba Cloud which region to use when deploying resources.
|
||||||
|
|
||||||
|
The region can be any
|
||||||
|
[Alibaba Cloud region](https://www.alibabacloud.com/help/en/cloud-migration-guide-for-beginners/latest/regions-and-zones) code.
|
||||||
|
|
||||||
|
Use `kubectl get vpcs` to verify Crossplane created the VPC.
|
||||||
|
|
||||||
|
{{< hint type="tip" >}}
|
||||||
|
Crossplane created the vpc when the values READY and SYNCED are True.
|
||||||
|
This may take up to 1 minutes.
|
||||||
|
{{< /hint >}}
|
||||||
|
```shell {label="getVpc",copy-lines="all"}
|
||||||
|
$ kubectl get vpcs
|
||||||
|
NAME SYNCED READY EXTERNAL-NAME AGE
|
||||||
|
crossplane-vpc True True vpc-8vb3c******** 15s
|
||||||
|
```
|
||||||
|
|
||||||
|
## Delete the managed resource
|
||||||
|
Before shutting down your Kubernetes cluster, delete the VPC just created.
|
||||||
|
|
||||||
|
Use `kubectl delete vpc <vpc name>` to remove the vpc.
|
||||||
|
|
||||||
|
```shell {label="deleteVpc",copy-lines="all"}
|
||||||
|
$ kubectl delete vpc crossplane-vpc
|
||||||
|
vpc.vpc.alibabacloud.crossplane.io "crossplane-vpc" deleted
|
||||||
|
```
