Extended description

Creates a new context. This allows you to quickly switch the cli configuration to connect to different clusters or single nodes.

To create a context from scratch provide the docker and, if required, kubernetes options. The example below creates the context my-context with a docker endpoint of /var/run/docker.sock and a kubernetes configuration sourced from the file /home/me/my-kube-config:

$ docker context create my-context \
      --docker host=/var/run/docker.sock \
      --kubernetes config-file=/home/me/my-kube-config

Use the --from=<context-name> option to create a new context from an existing context. The example below creates a new context named my-context from the existing context existing-context:

$ docker context create my-context --from existing-context

If the --from option is not set, the context is created from the current context:

$ docker context create my-context

This can be used to create a context out of an existing DOCKER_HOST based script:

$ source my-setup-script.sh
$ docker context create my-context

To source only the docker endpoint configuration from an existing context use the --docker from=<context-name> option. The example below creates a new context named my-context using the docker endpoint configuration from the existing context existing-context and a kubernetes configuration sourced from the file /home/me/my-kube-config:

$ docker context create my-context \
      --docker from=existing-context \
      --kubernetes config-file=/home/me/my-kube-config

To source only the kubernetes configuration from an existing context use the --kubernetes from=<context-name> option. The example below creates a new context named my-context using the kuberentes configuration from the existing context existing-context and a docker endpoint of /var/run/docker.sock:

$ docker context create my-context \
      --docker host=/var/run/docker.sock \
      --kubernetes from=existing-context

Docker and Kubernetes endpoints configurations, as well as default stack orchestrator and description can be modified with docker context update
