\tWe recommend installing Docker (and Compose) directly from Docker.com instead of your Operation System package registry.
|
|
\tPlease see $(highlight "https://docs.docker.com/engine/install/")${RED} for information on how to install Docker on your system.
|
|
|
|
\tA convinience script is provided by Docker to automate the installation that should work on all supported platforms:
|
|
|
|
\t\t ${GREEN}\$${BLUE} curl -fsSL https://get.docker.com -o get-docker.sh
|
|
\t\t ${GREEN}\$${BLUE} sudo sh ./get-docker.sh
|
|
${RED}
|
|
\tPlease see $(highlight "https://docs.docker.com/engine/install/ubuntu/#install-using-the-convenience-script")${RED} for more information
|
|
|
|
\tAlternatively, you can update *JUST* the Compose plugin by following the guide here:
|
|
\t$(highlight "https://docs.docker.com/compose/install/linux/#install-the-plugin-manually")${RED}
|
|
|
|
\tLearn more about Docker compose release history here:
