+# OSC Packaging Container
+
+{% include 'badges.j2' %}
+
+This is the openSUSE packaging container image that includes all the required
+tools for creating and modifying packages in the [Open Build
+Service](https://build.opensuse.org/) using
+[osc](https://github.com/openSUSE/osc/).
+
+
+## How to use this container image
+
+The container image is intended for interactive usage with a `.oscrc` configuration file and
+the osc cookiejar mounted into the container:
+
+```ShellSession
+# podman run --rm -it \
+      -v ~/.config/osc/oscrc:/root/.config/osc/oscrc:ro,z \
+      -v ~/.local/state/osc/cookiejar:/root/.local/state/osc/cookiejar:rw,z \
+      {{ image.pretty_reference }}
+```
+
+The command launches an interactive shell environment that uses the local osc
+configuration. You can then check out packages, perform modifications, and send
+submissions to OBS.
+
+To work on an already checked out package, mount the current working directory:
+
+```ShellSession
+# podman run --rm -it \
+      -v ~/.config/osc/oscrc:/root/.config/osc/oscrc:ro,z \
+      -v ~/.local/state/osc/cookiejar:/root/.local/state/osc/cookiejar:z \
+      -v .:/root/osc-workdir:z \
+      {{ image.pretty_reference }}
+```
+
+The container entrypoint recognizes whether you are launching it for interactive
+usage or invoking `osc` directly. You can omit the command `osc` in the second
+case. For example:
+
+```ShellSession
+# podman run --rm -it \
+      -v ~/.config/osc/oscrc:/root/.config/osc/oscrc:ro,z \
+      -v ~/.local/state/osc/cookiejar:/root/.local/state/osc/cookiejar:z \
+      {{ image.pretty_reference }} \
+          ls openSUSE:Factory
+```
+
+The command automatically forwards the arguments to `osc` and calls
+`osc ls openSUSE:Factory`.
+
+
+### Building packages
+
+The container image can be used to build packages using the podman build
+backend. You **must** launch the container in privileged mode for building.
+
+
+### Using the image labels
+
+The image provides two labels: `run` and `runcwd`. The first includes the full
+command, to run the `osc` container, while the second to run the container with
+the local working directory mounted.
+
+To view the labels, use the following command:
+
+```ShellSession
+# podman container runlabel run --display {{ image.pretty_reference }}
+# podman container runlabel runcwd --display {{ image.pretty_reference }}
+```
+
+The labels can be used to run the container with Podman version 5.1.0 or later:
+```ShellSession
+# podman container runlabel run \
+      {{ image.pretty_reference }} \
+          ls openSUSE:Factory
+```
+
+
+### Connecting to build.suse.de
+
+build.suse.de uses an SSH-based authentication, which requires additional
+resources to be available in the container. You also must provide the internal certificate to the container:
+
+```ShellSession
+# podman run --rm -it \
+      -v ~/.config/osc/oscrc:/root/.config/osc/oscrc:ro,z \
+      -v ~/.local/state/osc/cookiejar:/root/.local/state/osc/cookiejar:z \
+      -v /etc/ssl/ca-bundle.pem:/etc/ssl/ca-bundle.pem:ro,z \
+      -v $SSH_AUTH_SOCK:/run/user/0/ssh-agent.socket:z \
+      -e SSH_AUTH_SOCK=/var/run/user/0/ssh-agent.socket:z \
+      -v "$PWD":/root/osc-workdir:z \
+      {{ image.pretty_reference }}
+```
+
+
+## Limitations
+
+- Currently, it is not possible to build packages in a container.
+- The `runlabel run` command only works with Podman 5.1.0 and newer.
+
+
+## Volumes
+
+The container image is preconfigured to put `/var/tmp` into a volume. This
+directory is used by `osc` to store the buildroot and the package cache.
