Docker Universal Control Plane Tool
|
|
|
|
This tool has commands to 'install' and 'uninstall' UCP.
|
|
This tool must run as a container with a well-known name and with the
|
|
`docker.sock` volume mounted, which you can cut-and-paste from the usage
|
|
example below.
|
|
|
|
This tool will generate TLS certificates. The tool may not be able to
|
|
discover your externally visible fully qualified hostname. For proper
|
|
certificate verification, you should pass one or more Subject Alternative
|
|
Names with '--san' during 'install'. These names should match the fully qualified
|
|
hostname you intend to use to access the given system.
|
|
|
|
Many settings can be passed as flags or environment variables. When passing as
|
|
an environment variable, use the 'docker run -e VARIABLE_NAME ...' syntax to
|
|
pass the value from your shell, or 'docker run -e VARIABLE_NAME=value ...' to
|
|
specify the value explicitly on the command line.
|
|
|
|
Additional help is available for each command with the '--help' option.
|
|
|
|
