func (*DockerCli) CurrentContext 

func (cli *DockerCli) CurrentContext() string

CurrentContext returns the current context name, based on flags, environment variables and the cli configuration file, in the following order of preference:

  1. The "--context" command-line option.
  2. The "DOCKER_CONTEXT" environment variable.
  3. The current context as configured through the in "currentContext" field in the CLI configuration file ("~/.docker/config.json").
  4. If no context is configured, use the "default" context.

Fallbacks for backward-compatibility

To preserve backward-compatibility with the "pre-contexts" behavior, the "default" context is used if:

  • The "--host" option is set
  • The "DOCKER_HOST" (DefaultContextName) environment variable is set to a non-empty value.

In these cases, the default context is used, which uses the host as specified in "DOCKER_HOST", and TLS config from flags/env vars.

Setting both the "--context" and "--host" flags is ambiguous and results in an error when the cli is started.

CurrentContext does not validate if the given context exists or if it's valid; errors may occur when trying to use it.
