Introduce go generate to embed static templates (#2189)
# Problem
In order to switch Linkerd template rendering to use `.yaml` files, static
assets must be bundled in the Go binary for use by `linkerd install`.

# Solution
The solution should not affect the local development process of building and
testing.

[vfsgen](https://github.com/shurcooL/vfsgen) generates Go code that statically
implements the provided `http.FileSystem`. Paired with `go generate` and Go
[build tags](https://golang.org/pkg/go/build/), we can continue to use the
template files on disk when developing with no change required.

In `!prod` Go builds, the `cli/static/templates.go` file provides a
`http.FileSystem` to the local templates. In `prod` Go builds, `go generate
./cli` generates `cli/static/generated_templates.gogen.go` that statically
provides the template files.

When built with `-tags prod`, the executable will be built with the staticlly
generated file instead of the local files.

# Validation
The binaries were compiled locally with `bin/docker-build`. The binaries were
then tested with `bin/test-run (pwd)/target/cli/darwin/linkerd`. All tests
passed.

No change was required to successfully run `bin/go-run cli install`. No change
was required to run `bin/linkerd install`.

Fixes #2153

Configure proxy keepalives via the environment (#2193)
In linkerd/linkerd2-proxy#186, the proxy supports configuration of TCP
keepalive values.

This change sets `LINKERD2_PROXY_INBOUND_ACCEPT_KEEPALIVE` and
`LINKERD2_PROXY_OUTBOUND_CONNECT_KEEPALIVE` to 10s when injecting the
proxy, so that remote connections are configured with a keepalive.

This configuration is NOT yet exposed through the CLI. This may be done
in a followup, if necessary.

Fixes #1949

Use the proper controller identity when configuring pods with TLS (#2196)
Since 37ae423, deployments have been prefixed with linkerd-; however
the inject logic was not changed to take this into consideration when
constructing the controller's identity.

This means that the proxy's client to the control plane has been unable to
establish TLS'd communcation to the proxy-api. Previously, the proxy would
silently fall back to plaintext, but in master this behavior recently changed to
be stricter, so this bug will prevent the proxy from connecting to proxy-api
in any way.

Cody Vandermyn 906c3cbfc5 WIP: CNI Plugin (#2071)
* Export RootOptions and BuildFirewallConfiguration so that the cni-plugin can use them.
* Created the cni-plugin based on istio-cni implementation
* Create skeleton files that need to be filled out.
* Create the install scripts and finish up plugin to write iptables
* Added in an integration test around the install_cni.sh and updated the script to handle the case where it isn't the only plugin. Removed the istio kubernetes.go file in favor of pkg/k8s; initial usage of this package; found and fixed the typo in the ClusterRole and ClusterRoleBinding; found the docker-build-cni-plugin script
* Corrected an incorrect name in the docker build file for cni-plugin
* Rename linkerd2-cni to linkerd-cni
* Fixup Dockerfile and clean up code a bit as well as logging statements.
* Update Gopkg.lock after master merge.
* Update test file to remove temporary tag.
* Fixed the command to run during the test while building up the docker run.
* Added attributions to applicable files; in the test file, use a different container for each test scenario and also print the docker logs to stdout when there is an error;
* Add the --no-init-container flag to install and inject. This flag will not output the initContainer and will add an annotation assuming that the cni will be used in this case.
* Update .travis.yml to build the cni-plugin docker image before running the tests.
* Workaround golint warnings.
* Create a new command to install the linkerd-cni plugin.
* Add the --no-init-container option to linkerd inject
* Use the setup ip tables annotation during the proxy auto inject webhook prevent/allow addition of an init container; move cni-plugin tests to the integration-test section of travis
* gate the cni-plugin tests with the -integration-tests flag; remove unnecessary deployment .yaml file.
* Incorporate PR Cleanup suggestions.
* Remove the SetupIPTablesLabel annotation and use config flags and the presence of the init container to determine whether the cni-plugin writes ip tables.
* Fix a logic bug in the cni-plugin code that prevented the iptables from being written; Address PR comments; make tests pass.
* Update go deps shas
* Changed the single file install-cni plugin filename to be .conf vs .conflist; Incorporated latest PR comments around spacing with the new renderer among others.
* Fix an issue with renaming .conf to .conflist when needed.
* Renamed some of the variables to try to make it more clear what is going on.

Refactor `install`'s `render` output to be helm compatible (#2098)
# Problem
In order to refactor `install` to allow for a more flexible configuration, we
should start with the format of the YAML that it renders. Using the Helm
YAML format will make it easier add flexible configuration options in the
future. Currently, the rendered template that `install` produces does not
follow this format.

# Solution
Use the internals that Helm itself uses to render an inject template that
follows the same formatting rules. Helm's `template` cmd provides a good
outline of what is needed to make Linkerd's `install` cmd work as if it was
a Chart.

# Validation
There are no new tests, but there may not be anything to test at this stage.
This is a WIP PR towards the ultimate goal of `install` allowing a more
flexible configuration.

However, `install` now uses all the Helm `template` internals and therefore
satisfies the needed properties for Helm Charts.

Remove proxy bind timeout from CLIs (#2017)
This branch removes the `--proxy-bind-timeout` flag from the 
`linkerd inject` and `linkerd install` CLI commands, and the
`LINKERD2_PROXY_BIND_TIMEOUT` environment variable from their output.
This is in preparation for removing that timeout from the proxy (as
described in #2013). 

I thought it was prudent to remove this from the CLIs before removing it
from the proxy, so we can't create a situation where the CLIs produce
output that results in broken proxy containers.

Fix Unicode and color output for Windows (#2114)
The default font in Windows console did not support the Unicode
characters recently added to check and inject commands. Also the color
library the linkerd cli depends on was not being used in a
cross-platform way.

Replace the existing Unicode characters used in `check` and `inject`
with characters available in most fonts, including Windows console.
Similarly replace the spinner used in `check` with one that uses
characters available in most fonts.

Modify `check` and `inject` to use `color.Output` and `color.Error`,
which wrap `os.Stdout` and `os.Stderr`, and perform special
tranformations when on Windows.

Add a `--no-color` option to `linkerd logs`. While stern uses the same
color library that `check`/`inject` use, it is not yet using the
`color.Output` API for Windows support. That issue is tracked at:

Improve routes command to list all routes (#2066)
Fixes #1875 

This change improves the `linkerd routes` command in a number of important ways:

* The restriction on the type of the `--to` argument is lifted and any resource type can now be used.  Try `--to ns/books`, `--to po/webapp-ABCDEF`, `--to au/linkerd.io`, or even `--to svc`.
* All routes for the target will now be populated in the table, even if there are no Prometheus metrics for that route.
* [UNKNOWN] has been renamed to [DEFAULT]
* The `Service/Authority` column will now list `Service` in all cases except for when an authority target is explicitly requested.

This is all made possible by a shift in the way we handle the destination resource.  When we get a request with a `ToResource`, we use the k8s API to find all Services which include at least one pod belonging to that resource.  We then fetch all service profiles for those services and display the routes from those serivce profiles.  

This shift in thinking also precipitates a change in the TopRoutes API where we no longer need special cases for `ToAll` (which can be specified by `--to au`) or `ToAuthority` (which can be specified by `--to au/<authority>`) and instead can use a `ToResource` to handle all cases.

between successful and failed executions, and were a bit verbose and
challenging to parse.

Reorganize output of `check` and `inject` commands, to provide more

Specific changes:

`linkerd check`
- visually group checks by category
- introduce `hintURL`'s, to provide doc links when checks fail
- add spinners when retrying, remove additional retry lines
- colored unicode characters to indicate success/warning/failure

`linkerd inject`

Added `linkerd uninject` command (#2054)
Add `linkerd uninject` command

uninject.go iterates through the resources annotations, labels,
initContainers and Containers, removing what we know was injected by
linkerd.

The biggest part of this commit is the refactoring of inject.go, to make
it more generic and reusable by uninject.

The idea is that in a following PR this functionality will get reused by
`linkerd inject` to uninject as as preliminary step to injection, as a
solution to #1970.

This was tested successfully on emojivoto with:

```
1) inject:
kubectl get -n emojivoto deployment -o yaml | bin/linkerd inject - |
kubectl apply -f -
2) uninject:
kubectl get -n emojivoto deployment -o yaml | bin/linkerd uninject - |
kubectl apply -f -
```

Also created unit tests for uninject.go. The fixture files from the inject
tests could be reused. But as now the input files act as outputs, they
represent existing resources and required these changes (that didn't
affect inject):
  - Rearranged fields in alphabetical order.
  - Added fields that are only relevant for existing resources (e.g.
    creationTimestamp and status.replicas in StatefulSets)

Support service profiles for external authorities (#1928)
Add support for service profiles created on external (non-service) authorities.  For example, this allows you to create a service profile named `linkerd.io` which will apply to calls made to `linkerd.io`.

This is done by changing the `LINKERD2_PROXY_DESTINATION_PROFILE_SUFFIXES` to `.` so that the proxy will attempt to lookup a service profile for any authority.  We provide the `--disable-external-profiles` proxy flag to revert this behavior in case it is a problem.

We also refactor the proxy-api implementation of GetProfiles so that it does the profile lookup, regardless of if the authority looks like a Kubernetes service name or not.  To simplify this, support for multiple resolves (which was unused) was removed.

install: Add a -disable-h2-upgrade flag (#1926)
The proxy-api service _always_ suggests that two meshed pods communicate
via HTTP/2 (i.e. via transparent protocol upgrading, if necessary).
This can complicate debugging and diagnostics at times, so it's
important that we have a way to deploy linkerd without this auto-upgrade
behavior.

This change adds a `-disable-h2-upgrade` flag to the `linkerd install`
command that disables transparent upgrading for the whole cluster.

Add filtering by job in stat, tap, top; fix panic (#1904)
Filtering by Kubernetes job was not supported. Also filtering by any unknown

Fix panic when unknown type specified as a `--from` or `--to` flag.

Fix `job` label from `linkerd-proxy` overwriting Prometheus `job` label at
collection time. This caused all metrics collected by proxy sidecars in
Kubernetes jobs to be collected into an incorrect Prometheus job, rather than
the expected `linkerd-proxy` Prometheus job.

Fix `unsupported resource type` tap error message incorrectly printing the
target resource rather than the destination.

Set `--controller-log-level debug` in `install_test.go` for easier debugging.

Expose `slow-cooker`'s metrics via a k8s service in the tap integration test, to
validate proxy requests with a job as destination.

Adjust proxy, Prometheus, and Grafana probes (#1899)
* Adjust proxy, Prometheus, and Grafana probes

High `readinessProbe.initialDelaySeconds` values delayed the controller's
readiness by up to 30s, preventing cli commands from succeeding shortly after
control plane deployment.

Decrease `readinessProbe.initialDelaySeconds` in the proxy, Prometheus, and
Grafana to the default 0s. Also change `linkerd check` controller pod ordering
to: controller, prometheus, web, grafana.

Detailed probe changes:
- proxy
  - decrease `readinessProbe.initialDelaySeconds` from 10s to 0s
- prometheus
  - decrease `readinessProbe.initialDelaySeconds` from 30s to 0s
  - decrease `readinessProbe.timeoutSeconds` from 30s to 1s
  - decrease `livenessProbe.timeoutSeconds` from 30s to 1s
- grafana
  - decrease `readinessProbe.initialDelaySeconds` from 30s to 0s
  - decrease `readinessProbe.timeoutSeconds` from 30s to 1s
  - decrease `readinessProbe.failureThreshold` from 10 to 3
  - increase `livenessProbe.initialDelaySeconds` from 0s to 30s

Add TopRoutes method the the public api and route CLI command to consume it (#1860)
Add a routes command which displays per-route stats for services that have service profiles defined.

This change has three parts:
* A new public-api RPC called `TopRoutes` which serves per-route stat data about a service
* An implementation of TopRoutes in the public-api service.  This implementation reads per-route data from Prometheus.  This is very similar to how the StatSummaries RPC and much of the code was able to be refactored and shared.
* A new CLI command called `routes` which displays the per-route data in a tabular or json format.  This is very similar to the `stat` command and much of the code was able to be refactored and shared.

Note that as of the currently targeted proxy version, only outbound route stats are supported so the `--from` flag must be included in order to see data.  This restriction will be lifted in an upcoming change once we add support for inbound route stats as well.

Remove the proxy-api container (#1813)
A container called `proxy-api` runs in the Linkerd2 controller pod.  This container listens on port 8086 and serves the proxy-api but does nothing other than forward gRPC requests to the destination container which listens on port 8089.

We remove the proxy-api container altogether and change the destination container to listen on port 8086 instead of 8089.  The result is that clients still use the proxy-api by connecting to `proxy-api.<ns>.svc.cluster.local:8086` but the controller has one fewer containers.  This results in a simpler system that is easier to reason about.

Ivan Sim 4fba6aca0a Proxy init and sidecar containers auto-injection (#1714)
* Support auto sidecar-injection

1. Add proxy-injector deployment spec to cli/install/template.go
2. Inject the Linkerd CA bundle into the MutatingWebhookConfiguration
during the webhook's start-up process.
3. Add a new handler to the CA controller to create a new secret for the
webhook when a new MutatingWebhookConfiguration is created.
4. Declare a config map to store the proxy and proxy-init container
specs used during the auto-inject process.
5. Ignore namespace and pods that are labeled with
linkerd.io/auto-inject: disabled or linkerd.io/auto-inject: completed
6. Add new flag to `linkerd install` to enable/disable proxy
auto-injection

Proposed implementation for #561.

* Resolve missing packages errors
* Move the auto-inject label to the pod level
* PR review items
* Move proxy-injector to its own deployment
* Ignore pods that already have proxy injected

This ensures the webhook doesn't error out due to proxy that are injected using the  command

* PR review items on creating/updating the MWC on-start
* Replace API calls to ConfigMap with file reads
* Fixed post-rebase broken tests
* Don't mutate the auto-inject label

Since we started using healhcheck.HasExistingSidecars() to ensure pods with
existing proxies aren't mutated, we don't need to use the auto-inject label as
an indicator.

This resolves a bug which happens with the kubectl run command where the deployment
is also assigned the auto-inject label. The mutation causes the pod auto-inject
label to not match the deployment label, causing kubectl run to fail.

* Tidy up unit tests
* Include proxy resource requests in sidecar config map
* Fixes to broken YAML in CLI install config

The ignore inbound and outbound ports are changed to string type to
avoid broken YAML caused by the string conversion in the uint slice.

Also, parameterized the proxy bind timeout option in template.go.

Renamed the sidecar config map to
'linkerd-proxy-injector-webhook-config'.

Only tap pods that are meshed (#1535)
Previously, we would tap any resource's pods, regardless of whether the pods
were meshed or not. We can't actually tap non-meshed pods, so I'm adding a check
that will filter out non-meshed pods from the pods that tap watches.

Previous behaviour:
When attempting to hang a non meshed pod, it would establish
a watch on the pods, but then never return any results. In the CLI you could
just cancel it with Ctrl-C. In the web, clicking Stop would send a
WebSocket.close(1000) but wouldn't actually close the connection... 

Behaviour after change :
If no pods under the specified resource are meshed, it'll
return an error of no pods being found to tap

Add resource metadata to Tap CLI output (#1437)
Closes #1170.

This branch adds a `-o wide` (or `--output wide`) flag to the Tap CLI.
Passing this flag adds `src_res` and `dst_res` elements to the Tap
output, as described in #1170. These use the metadata labels in the tap
event to describe what Kubernetes resource the source and destination
peers belong to, based on what resource type is being tapped, and fall
back to pods if either peer is not a member of the specified resource
type.

In addition, when the resource type is not `namespace`, `src_ns` and
`dst_ns` elements are added, which show what namespaces the the source
and destination peers are in. For peers which are not in the Kubernetes
cluster, none of these labels are displayed.

The source metadata added in #1434 is used to populate the `src_res` and
`src_ns` fields.

Also, this branch includes some refactoring to how tap output is
formatted.

Increase outbound router capacity for Prometheus pod's proxy (#1358)
Currently, when a cluster has over 100 pods injected with the Linkerd2
proxy, Prometheus metrics are not collected correctly. This is because
Prometheus appears to be making more concurrent requests than its'
proxy's outbound router cache can handle See issue #1322 for further 
details.

This branch introduces a workaround for this issue, by increasing the
outbound router cache capacity to 10000 routes for the Prometheus pod's
proxy only. The router capacity limit of 100 active routes is primarily
due to the limitation of the number of active Destination service 
lookups, so increasing the capacity for the Prometheus pod specifically
is probably okay, as the scrape requests are made to IP addresses 
directly and therefore will not cause service discovery lookups. 

This change was originally implemented and tested in @siggy's PR #1228.
I've rebased his branch onto the current `master`, and updated the code
to reflect the project name change.

Enable get for nodes/proxy for Prometheus RBAC (#1142)
The `kubernetes-nodes-cadvisor` Prometheus queries node-level data via
the Kubernetes API server. In some configurations of Kubernetes, namely
minikube and at least one baremetal kubespray cluster, this API call
requires the `get` verb on the `nodes/proxy` resource.

Enable `get` for `nodes/proxy` for the `conduit-prometheus` service
account.

None of the zone configuration is tested and lots of things assume the cluster

* Remove the CONDUIT_PROXY_DESTINATIONS_AUTOCOMPLETE_FQDN setting

The way that Kubernetes configures DNS search suffixes has some negative
consequences as some names like "example.com" are ambiguous: depending on
whether there is a service "example" in the "com" namespace, "example.com"
may refer to an external service or an internal service, and this can
fluctuate over time. In recognition of that we added the
CONDUIT_PROXY_DESTINATIONS_AUTOCOMPLETE_FQDN setting, thinking this would
be part of a solution for users to opt out of the unfortunate behavior
if their applications didn't depend on the DNS search suffix feature.

It turns out similar effects can be acheived using a custom dnsConfig,
starting in Kubernetes 1.10 when dnsConfig reaches the beta stability level.
Now any CONDUIT_PROXY_DESTINATIONS_AUTOCOMPLETE_FQDN-based seems duplicative.
Further, attempting to support it optionally made the code complex and hard
to read.

Therefore, let's just remove it. If/when somebody actually requests this
functionality then we can add it back, if dnsConfig isn't a valid alternative
for them.

Make absolute names truly absolute. (#525)
Kubernetes will do multiple DNS lookups for a name like
`proxy-api.conduit.svc.cluster.local` based on the default search settings
in /etc/resolv.conf for each container:

1. proxy-api.conduit.svc.cluster.local.conduit.svc.cluster.local. IN A
2. proxy-api.conduit.svc.cluster.local.svc.cluster.local. IN A
3. proxy-api.conduit.svc.cluster.local.cluster.local. IN A
4. proxy-api.conduit.svc.cluster.local. IN A

We do not need or want this search to be done, so avoid it by making each
name absolute by appending a period so that the first three DNS queries
are skipped for each name.

The case for `localhost` is even worse because we expect that `localhost` will
always resolve to 127.0.0.1 and/or ::1, but this is not guaranteed if the default
search is done:

1. localhost.conduit.svc.cluster.local. IN A
2. localhost.svc.cluster.local. IN A
3. localhost.cluster.local. IN A
4. localhost. IN A

Avoid these unnecessary DNS queries by making each name absolute, so that the
first three DNS queries are skipped for each name.

The init container injected by conduit inject rewrites the iptables configuration for its network namespace. This causes havoc when the network namespace isn't restricted to the pod, i.e. when hostNetwork=true.

Skip pods with hostNetwork=true to avoid this problem.

Fixes #366.

Refactor `conduit inject` code to make it unit-testable. (#379)
Refactor `conduit inject` code to make it unit-testable.

Refactor the conduit inject code to make it easier to add unit tests. This work was done by @deebo91 in #365. This is the same PR without the conduit install changes, so that it can land ahead of #365. In particular, this will be used for testing the fix for high-priority bug #366.

Remove pod-level metrics from web and CLI (#304)
This PR updates the web UI to remove the pod detail page, and to remove the links to that page from pod names in metrics tables. It also removes the `pods` option from `conduit stat`, and the `sourcePod` and `targetPod` fields from the controller API proto's `MetricMetadata` message.

I've updated the `conduit stat` tests to reflect these changes, and manually verified the web UI changes.

Closes #261

Simplify and refactor k8s labels and annnotations (#227)
The conduit.io/* k8s labels and annotations we're redundant in some
cases, and not flexible enough in others.

This change modifies the labels in the following ways:
`conduit.io/plane: control` => `conduit.io/controller-component: web`
`conduit.io/controller: conduit` => `conduit.io/controller-ns: conduit`
`conduit.io/plane: data` => (remove, redundant with `conduit.io/controller-ns`)
It also centralizes all k8s labels and annotations into
pkg/k8s/labels.go, and adds tests for the install command.

Part of #201
