NAME¶

oc set image-lookup - Change how images are resolved when deploying applications

SYNOPSIS¶

oc set image-lookup [OPTIONS]

DESCRIPTION¶

Use an image stream from pods and other objects.

Image streams make it easy to tag images, track changes from other registries, and centralize access control to images. Local name lookup allows an image stream to be the source of images for pods, deployments, replica sets, and other resources that reference images, without having to provide the full registry URL. If local name lookup is enabled for an image stream named 'mysql', a pod or other resource that references 'mysql:latest' (or any other tag) will pull from the location specified by the image stream tag, not from an upstream registry.

Once lookup is enabled, simply reference the image stream tag in the image field of the object. For example:

    $ oc import-image mysql:latest --confirm


    $ oc set image-lookup mysql


    $ oc run mysql --image=mysql

will import the latest MySQL image from the DockerHub, set that image stream to handle the "mysql" name within the project, and then launch a deployment that points to the image we imported.

You may also force image lookup for all of the images on a resource with this command. An annotation is placed on the object which forces an image stream tag lookup in the current namespace for any image that matches, regardless of whether the image stream has lookup enabled.

    $ oc run mysql --image=myregistry:5000/test/mysql:v1


    $ oc tag --source=docker myregistry:5000/test/mysql:v1 mysql:v1


    $ oc set image-lookup deploy/mysql

Which should trigger a deployment pointing to the imported mysql:v1 tag.

OPTIONS¶

--all=false
If true, select all resources in the namespace of the specified resource types.

--allow-missing-template-keys=true
If true, ignore any errors in templates when a field or map key is missing in the template. Only applies to golang and jsonpath output formats.

--dry-run="none"
Must be "none", "server", or "client". If client strategy, only print the object that would be sent, without sending it. If server strategy, submit server-side request without persisting the resource.

--enabled=true
Mark the image stream as resolving tagged images in this namespace.

--field-manager="kubectl-set"
Name of the manager used to track field ownership.

-f, --filename=[]
Filename, directory, or URL to files to use to edit the resource

-k, --kustomize=""
Process the kustomization directory. This flag can't be used together with -f or -R.

--list=false
Display the current states of the requested resources.

--local=false
If true, operations will be performed locally.

-o, --output=""
Output format. One of: (json, yaml, name, go-template, go-template-file, template, templatefile, jsonpath, jsonpath-as-json, jsonpath-file).

-R, --recursive=false
Process the directory used in -f, --filename recursively. Useful when you want to manage related manifests organized within the same directory.

-l, --selector=""
Selector (label query) to filter on.

--show-managed-fields=false
If true, keep the managedFields when printing objects in JSON or YAML format.

--template=""
Template string or path to template file to use when -o=go-template, -o=go-template-file. The template format is golang templates [ ⟨http://golang.org/pkg/text/template/#pkg-overview⟩].

OPTIONS INHERITED FROM PARENT COMMANDS¶

--as=""
Username to impersonate for the operation. User could be a regular user or a service account in a namespace.

--as-group=[]
Group to impersonate for the operation, this flag can be repeated to specify multiple groups.

--as-uid=""
UID to impersonate for the operation.

--cache-dir="/home/abuild/.kube/cache"
Default cache directory

--certificate-authority=""
Path to a cert file for the certificate authority

--client-certificate=""
Path to a client certificate file for TLS

--client-key=""
Path to a client key file for TLS

--cluster=""
The name of the kubeconfig cluster to use

--context=""
The name of the kubeconfig context to use

--disable-compression=false
If true, opt-out of response compression for all requests to the server

--insecure-skip-tls-verify=false
If true, the server's certificate will not be checked for validity. This will make your HTTPS connections insecure

--kubeconfig=""
Path to the kubeconfig file to use for CLI requests.

--match-server-version=false
Require server version to match client version

-n, --namespace=""
If present, the namespace scope for this CLI request

--profile="none"
Name of profile to capture. One of (none|cpu|heap|goroutine|threadcreate|block|mutex)

--profile-output="profile.pprof"
Name of the file to write the profile to

--request-timeout="0"
The length of time to wait before giving up on a single server request. Non-zero values should contain a corresponding time unit (e.g. 1s, 2m, 3h). A value of zero means don't timeout requests.

-s, --server=""
The address and port of the Kubernetes API server

--tls-server-name=""
Server name to use for server certificate validation. If it is not provided, the hostname used to contact the server is used

--token=""
Bearer token for authentication to the API server

--user=""
The name of the kubeconfig user to use

--warnings-as-errors=false
Treat warnings received from the server as errors and exit with a non-zero exit code

EXAMPLE¶

  # Print all of the image streams and whether they resolve local names


  oc set image-lookup


  


  # Use local name lookup on image stream mysql


  oc set image-lookup mysql


  


  # Force a deployment to use local name lookup


  oc set image-lookup deploy/mysql


  


  # Show the current status of the deployment lookup


  oc set image-lookup deploy/mysql --list


  


  # Disable local name lookup on image stream mysql


  oc set image-lookup mysql --enabled=false


  


  # Set local name lookup on all image streams


  oc set image-lookup --all
