|---|---|
| Usage | docker context show |
Description
Print the name of the current context, possibly set by DOCKER_CONTEXT environment
variable or --context global option.
Examples
Print the current context
The following example prints the currently used
docker context:
$ docker context show'
default
As an example, this output can be used to dynamically change your shell prompt to indicate your active context. The example below illustrates how this output could be used when using Bash as your shell.
Declare a function to obtain the current context in your ~/.bashrc, and set
this command as your PROMPT_COMMAND
function docker_context_prompt() {
PS1="context: $(docker context show)> "
}
PROMPT_COMMAND=docker_context_prompt
After reloading the ~/.bashrc, the prompt now shows the currently selected
docker context:
$ source ~/.bashrc
context: default> docker context create --docker host=unix:///var/run/docker.sock my-context
my-context
Successfully created context "my-context"
context: default> docker context use my-context
my-context
Current context is now "my-context"
context: my-context> docker context use default
default
Current context is now "default"
context: default>
