Create Working Directory

sealos create is a command in the Sealos command line tool, mainly used for creating the cluster working directory without executing the CMD, so as to review the image. This guide will detail its usage and options.

Basic Usage​

The sealos create command is used to create a cluster working directory but does not actually run, mainly used for debugging or testing. It can output the address of the cluster image, you can check whether the content of the cluster image is consistent with the expectation.

sealos create docker.io/labring/kubernetes:v1.24.0

In the above command, clustername represents the name of the cluster you want to create.

Options​

The sealos create command provides the following options:

  • -c, --cluster='default': The name of the cluster to be created but not actually run. The default is default.

  • --platform='linux/arm64/v8': Set the operating system/architecture/version of the image to the provided value, rather than the current operating system and architecture of the host (for example, linux/arm).

  • --short=false: If true, only print the mount path.

  • -e, --env=[]: Specify environment variables used during the rendering of template files.

Each option can be followed by an argument.

Example​

For example, you can use the following command to create a cluster named mycluster, but do not actually run it:

sealos create -e registryPort=8443 docker.io/labring/kubernetes:v1.24.0

This command will create a cluster working directory with an image name of docker.io/labring/kubernetes:v1.24.0 and output the address of the cluster image. The -e registryPort=8443 option specifies the environment variable used during the rendering of template files, where registryPort is set to 8443. Please note that in this example, the cluster is not actually run.
