* Add shell completion with cobraPaul Holzinger2020-11-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allow automatic generation for shell completion scripts with the internal cobra functions (requires v1.0.0+). This should replace the handwritten completion scripts and even adds support for fish. With this approach it is less likley that completions and code are out of sync. We can now create the scripts with - podman completion bash - podman completion zsh - podman completion fish To test the completion run: source <(podman completion bash) The same works for podman-remote and podman --remote and it will complete your remote containers/images with the correct endpoints values from --url/--connection. The completion logic is written in go and provided by the cobra library. The completion functions lives in `cmd/podman/completion/completion.go`. The unit test at cmd/podman/shell_completion_test.go checks if each command and flag has an autocompletion function set. This prevents that commands and flags have no shell completion set. This commit does not replace the current autocompletion scripts. Closes #6440 Signed-off-by: Paul Holzinger <paul.holzinger@web.de>
* [CI:DOCS] Restore man page cross-checkerEd Santiago2020-11-11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Somewhere in the CIv2 migration we lost the man page vs --help cross-checker. Add it back, by adding it into the man-page-check Makefile target; this is part of 'make validate', which is run in CI even on CI:DOCS PRs. As happens when CI doesn't run, things broke. Man pages got out of sync with --help. This PR: 1) Fixes hack/xref-helpmsgs-manpages to deal with the new "Options" (instead of "Flags") form of podman help. #8034 did part of that, but one of my review comments was accidentally left out. 2) Fixes hack/xref-helpmsgs-manpages to deal with the new option syntax in man pages, post- #8292, in which each option is preceded by four hashes so as to make them HTML <h4> elements with named anchors. 3) Fixes man pages that #8292 accidentally missed. 4) Adds man page entries for two flags that got added to podman but not documented (pod create --network-alias, play kube --log-driver) Fixes: #8296 Signed-off-by: Ed Santiago <santiago@redhat.com>
* Use `bash` binary from env instead of /bin/bash for scriptsSascha Grunert2020-08-17
| | | | | | | | It's not possible to run any of the scripts on distributions which do have `bash` not in `/bin`. This is being fixed by using `/usr/bin/env bash` instead. Signed-off-by: Sascha Grunert <sgrunert@suse.com>
* auto updatesValentin Rothberg2020-03-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support to auto-update containers running in systemd units as generated with `podman generate systemd --new`. `podman auto-update` looks up containers with a specified "io.containers.autoupdate" label (i.e., the auto-update policy). If the label is present and set to "image", Podman reaches out to the corresponding registry to check if the image has been updated. We consider an image to be updated if the digest in the local storage is different than the one of the remote image. If an image must be updated, Podman pulls it down and restarts the container. Note that the restarting sequence relies on systemd. At container-creation time, Podman looks up the "PODMAN_SYSTEMD_UNIT" environment variables and stores it verbatim in the container's label. This variable is now set by all systemd units generated by `podman-generate-systemd` and is set to `%n` (i.e., the name of systemd unit starting the container). This data is then being used in the auto-update sequence to instruct systemd (via DBUS) to restart the unit and hence to restart the container. Note that this implementation of auto-updates relies on systemd and requires a fully-qualified image reference to be used to create the container. This enforcement is necessary to know which image to actually check and pull. If we used an image ID, we would not know which image to check/pull anymore.

* CI check for --help vs man pages: usability fixEd Santiago2019-04-08
| | | | | | | | | | | | | | | | | | | | | The output of this CI script leaves much to be desired: it is output from 'diff' with little clarity on what exactly is wrong. The proper fix is to make the output clear and readable: podman containers --help lists a 'foo' subcommand that is not present in docs/podman-containers.1.md Doing this in bash would take many hours and be fragile gibberish code. This does not seem worth the effort: the likely case is that breakages reported by this script will be due to a newly added subcommand, and the PR author will find it obvious what to do. Ergo, plan B: if the test fails, display a blurb at the end describing how to interpret results. Three minutes' effort, plus five for writing this commit message.

* add podman-healthcheck(1) to podman(1)Ed Santiago2019-03-07
| | | | | | | | | | | ...caught by hack/podman-commands.sh script. Which had a little buglet, which I fixed: add a special case for 'help', which neither has nor needs a man page. I believe the podman-commands.sh script is ready to be run in CI, hint hint. Signed-off-by: Ed Santiago <santiago@redhat.com>
* podman-commands script: refactorEd Santiago2019-02-28
| | | | | | | | | | | | | | | | | | | | | | | Make more general-purpose: instead of hardcoding a list of known subcommands, and duplicating sed pipelines for each, rely on 'podman help' itself to tell us which podman commands have subcommands; and examine each in turn. Should there ever be new subcommands, this will identify and test them. A special case is needed for 'podman image trust', whose documentation format doesn't match the others. The change to `common.go` fixes an inconsistency: the Usage message for commands with subcommands had an unnecessary blank line, making it harder to parse automatically. This simply produces consistent Usage messages for all podman commands. This script will not pass until #2480 is merged. After that, the goal is to add this as a CI hook.
