Upgrading docker rollout

All existing Docker Rollout versions are backward compatible. You can upgrade to the latest version by downloading the script again.

1. Check the current plugin version:

   ~/.docker/cli-plugins/docker-rollout docker-cli-plugin-metadata
   #=> ...
   #=> "Version": "v0.9",
   #=> ...
   

2. If new version is available, download the latest version:

   curl https://raw.githubusercontent.com/wowu/docker-rollout/master/docker-rollout -o ~/.docker/cli-plugins/docker-rollout
   

   You can check the latest version on the releases page.

3. You may need to make the file executable again:

   chmod +x ~/.docker/cli-plugins/docker-rollout
