'kubectl gs get releases' command reference

Note This command relates to our vintage product and is not relevant for Clusters based on Cluster API.

Like with all get commands in kubectl, this command can be used to get details on one item, a release in this case, or list several of them.

Usage

Get a list of releases

Execute

kubectl gs get releases

to list some information on all releases available to you in the current installation.

Here is some example output:

VERSION          STATUS       AGE   KUBERNETES  CONTAINER LINUX   COREDNS   CALICO
v14.2.1          ACTIVE       2d    1.19.9      2765.2.3          1.6.5     3.15.3
v14.2.2          ACTIVE       2d    1.19.9      2605.12.0         1.6.5     3.15.3
v15.0.0          DEPRECATED   3d    1.20.8      2765.2.6          1.6.5     3.15.3
v15.1.0          DEPRECATED   4d    1.20.9      2765.2.6          1.8.3     3.15.5
v15.1.1          DEPRECATED   4d    1.20.9      2765.2.6          1.8.3     3.15.5
v15.2.0          ACTIVE       20d   1.20.9      2765.2.6          1.8.3     3.15.5
v15.2.1          ACTIVE       21d   1.20.9      2765.2.6          1.8.3     3.15.5

Get specific release

When used with a release version as additional argument, the command will show details for a single release. Example:

kubectl gs get releases v15.2.1

Note: As an alternative to get releases, get release will also work.

Output

The standard tabular output format features these columns:

• VERSION: Unique identifier of the release.
• STATUS: The state of the release. Possible states are:
  • ACTIVE: A stable release, fully supported.
  • PREVIEW: A preview for testing purposes only, not yet considered stable.
  • WIP: Work in progress, a release in development.
  • DEPRECATED: Has been replaced by a successor release. No longer recommended.
• AGE: How long ago was the release created.
• KUBERNETES: The version of Kubernetes provided by this release
• CONTAINER LINUX: The version of container linux provided by this release
• COREDNS: The version of CoreDNS provided by this release
• CALICO: The version of Calico provided by this release

Flags

Here we document the flags that have a particular meaning for the get releases command. Use kubectl gs get releases --help for a full list.

--active-only

If present, list only the releases that are currently marked as active.

--output/-o

kubectl commonly allows to specify the output format for all get subcommands. kubectl gs get releases is no different. Similar to other get subcommands, you can specify the output format of kubectl gs get releases using the --output flag.

YAML output

To inspect a release’s main custom resource in YAML notation, add the --output yaml flag (or -o yaml in short) to the command.

The following example command would print the main resource for release v15.2.1.

kubectl gs get releases v15.2.1 --output yaml

When applied without a release version argument, the output will be a list of resources. Example:

$ kubectl gs get releases --output yaml
apiVersion: v1
kind: List
items:
- apiVersion: release.giantswarm.io/v1alpha1
  kind: Release
...
