context create

Create a context

Docker endpoint config:

NAME DESCRIPTION from Copy named context's Docker endpoint configuration host Docker endpoint on which to connect ca Trust certs signed only by this CA cert Path to TLS certificate file key Path to TLS key file skip-tls-verify Skip TLS certificate validation

Example:

$ docker context create my-context --description "some description" --docker "host=tcp://myserver:2376,ca=~/ca-file,cert=~/cert-file,key=~/key-file"

Options

Name	Type	Default	Description
--description	string		Description of the context
--docker	stringToString		set the docker endpoint
--from	string		create context from a named context

Description

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

Examples

Create a context with a docker endpoint (--docker)

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:

$ docker context create \
    --docker host=unix:///var/run/docker.sock \
    my-context

Create a context based on an existing context (--from)

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 --from existing-context my-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 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:

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

Docker endpoints configurations, as well as the description can be modified with docker context update.

Refer to the docker context update reference for details.
