I've been asked a couple times privately for information about this, so here's my current thinking on the project goals. must-have: 1. be able to exec (or otherwise connect to a container) and perform a 'yum update' of the container, commiting the results upon successful completion. eg - yum dockerupdate -y centos # run yum -y update in the centos:latest container. 2. Traditional yum interaction is expected (prompting for 'y/n', or accepting options like -y) 3. Passing exit values from the container to the host. 4. Exit with message on unsupported containers. 4. documentation and invalid-command syntax fails to usage/help. nice-to-have: 1. tab complete support for commands as well as available containers. 2. support for non-rpm based updates (support apt for debian/ubuntu based containers) questionable: glob/regex support to perform update on every matching container Comments/Questions? -- Jim Perrin The CentOS Project | http://www.centos.org twitter: @BitIntegrity | GPG Key: FA09AD77
