|
|
```
|
|
|
|
### Examples
|
|
|
|
```
|
|
|
|
# Create a service 'mysvc' using image at dev.local/ns/image:latest
|
|
kn service create mysvc --image dev.local/ns/image:latest
|
|
|
|
# Create a service with multiple environment variables
|
|
kn service create mysvc --env KEY1=VALUE1 --env KEY2=VALUE2 --image dev.local/ns/image:latest
|
|
|
|
# Create or replace a service 's1' with image dev.local/ns/image:v2 using --force flag
|
|
# if service 's1' doesn't exist, it's just a normal create operation
|
|
kn service create --force s1 --image dev.local/ns/image:v2
|
|
|
|
# Create or replace environment variables of service 's1' using --force flag
|
|
kn service create --force s1 --env KEY1=NEW_VALUE1 --env NEW_KEY2=NEW_VALUE2 --image dev.local/ns/image:v1
|
|
|
|
# Create service 'mysvc' with port 80
|
|
kn service create mysvc --port 80 --image dev.local/ns/image:latest
|
|
|
|
# Create or replace default resources of a service 's1' using --force flag
|
|
# (earlier configured resource requests and limits will be replaced with default)
|
|
# (earlier configured environment variables will be cleared too if any)
|
|
kn service create --force s1 --image dev.local/ns/image:v1
|
|
|
|
# Create a service with annotation
|
|
kn service create s1 --image dev.local/ns/image:v3 --annotation sidecar.istio.io/inject=false
|
|
```
|
|
|
|
### Options
|
|
|
|
```
|
|
--annotation stringArray Service annotation to set. name=value; you may provide this flag any number of times to set multiple annotations. To unset, specify the annotation name followed by a "-" (e.g., name-).
|
|
--arg stringArray Add argument to the container command. Example: --arg myArg1 --arg --myArg2 --arg myArg3=3. You can use this flag multiple times.
|
|
--async DEPRECATED: please use --no-wait instead. Create service and don't wait for it to become ready.
|
|
--autoscale-window string Duration to look back for making auto-scaling decisions. The service is scaled to zero if no request was received in during that time. (eg: 10s)
|
|
--cmd string Specify command to be used as entrypoint instead of default one. Example: --cmd /app/start or --cmd /app/start --arg myArg to pass aditional arguments.
|
|
--concurrency-limit int Hard Limit of concurrent requests to be processed by a single replica.
|
|
--concurrency-target int Recommendation for when to scale up based on the concurrent number of incoming request. Defaults to --concurrency-limit when given.
|
|
-e, --env stringArray Environment variable to set. NAME=value; you may provide this flag any number of times to set multiple environment variables. To unset, specify the environment variable name followed by a "-" (e.g., NAME-).
|
|
--env-from stringArray Add environment variables from a ConfigMap (prefix cm: or config-map:) or a Secret (prefix secret:). Example: --env-from cm:myconfigmap or --env-from secret:mysecret. You can use this flag multiple times. To unset a ConfigMap/Secret reference, append "-" to the name, e.g. --env-from cm:myconfigmap-.
|
|
--force Create service forcefully, replaces existing service if any.
|
|
-h, --help help for create
|
|
--image string Image to run.
|
|
-l, --label stringArray Service label to set. name=value; you may provide this flag any number of times to set multiple labels. To unset, specify the label name followed by a "-" (e.g., name-).
|
|
--limits-cpu string The limits on the requested CPU (e.g., 1000m).
|
|
--limits-memory string The limits on the requested memory (e.g., 1024Mi).
|
|
--lock-to-digest Keep the running image for the service constant when not explicitly specifying the image. (--no-lock-to-digest pulls the image tag afresh with each new revision) (default true)
|
|
--max-scale int Maximal number of replicas.
|
|
--min-scale int Minimal number of replicas.
|
|
--mount stringArray Mount a ConfigMap (prefix cm: or config-map:), a Secret (prefix secret: or sc:), or an existing Volume (without any prefix) on the specified directory. Example: --mount /mydir=cm:myconfigmap, --mount /mydir=secret:mysecret, or --mount /mydir=myvolume. When a configmap or a secret is specified, a corresponding volume is automatically generated. You can use this flag multiple times. For unmounting a directory, append "-", e.g. --mount /mydir-, which also removes any auto-generated volume.
|
|
-n, --namespace string Specify the namespace to operate in.
|
|
--no-lock-to-digest Do not keep the running image for the service constant when not explicitly specifying the image. (--no-lock-to-digest pulls the image tag afresh with each new revision)
|
|
--no-wait Create service and don't wait for it to become ready.
|
|
-p, --port int32 The port where application listens on.
|
|
--pull-secret string Image pull secret to set. An empty argument ("") clears the pull secret. The referenced secret must exist in the service's namespace.
|
|
--requests-cpu string The requested CPU (e.g., 250m).
|
|
--requests-memory string The requested memory (e.g., 64Mi).
|
|
--revision-name string The revision name to set. Must start with the service name and a dash as a prefix. Empty revision name will result in the server generating a name for the revision. Accepts golang templates, allowing {{.Service}} for the service name, {{.Generation}} for the generation, and {{.Random [n]}} for n random consonants. (default "{{.Service}}-{{.Random 5}}-{{.Generation}}")
|
|
--service-account string Service account name to set. An empty argument ("") clears the service account. The referenced service account must exist in the service's namespace.
|
|
--volume stringArray Add a volume from a ConfigMap (prefix cm: or config-map:) or a Secret (prefix secret: or sc:). Example: --volume myvolume=cm:myconfigmap or --volume myvolume=secret:mysecret. You can use this flag multiple times. To unset a ConfigMap/Secret reference, append "-" to the name, e.g. --volume myvolume-.
|
|
--wait-timeout int Seconds to wait before giving up on waiting for service to be ready. (default 600)
