dnf-plugin-container

Update containers like you update packages.

THIS IS A WORK IN PROGRESS In other words, this is a starting point for further work.

WIP Assumptions

• It may not work and possibly do weird things :-P
• Only tested with system containers so far
• The atomic commands libraries are available in the same site-packages that dnf uses
• Updates always update all containers to the latest version for the installed tag

Usage

WARNING This may break stuff!!

1. Create a path for plugins
2. Add pluginpath=$YOUR_NEW_PATH
3. Place container.pyin $YOUR_NEW_PATH
4. Use dnf container

Example

$ sudo atomic containers list --no-trunc
   CONTAINER ID IMAGE  COMMAND         CREATED          STATE      BACKEND    RUNTIME
   aaaaz test:0.4.rc2 /usr/bin/run.sh 2017-10-18 09:17 failed     ostree     runc
$ sudo atomic images list
   REPOSITORY   TAG       IMAGE ID       CREATED            VIRTUAL SIZE   TYPE
   test   0.4.rc2   2848e6699c97   2017-10-17 17:34                  ostree
$ sudo dnf container check
