* health check: add on-failure actionsValentin Rothberg2022-09-09
| | | | | | | | | | | | | | | | | | | | | | | | | | For systems that have extreme robustness requirements (edge devices, particularly those in difficult to access environments), it is important that applications continue running in all circumstances. When the application fails, Podman must restart it automatically to provide this robustness. Otherwise, these devices may require customer IT to physically gain access to restart, which can be prohibitively difficult. Add a new `--on-failure` flag that supports four actions: - **none**: Take no action. - **kill**: Kill the container. - **restart**: Restart the container. Do not combine the `restart` action with the `--restart` flag. When running inside of a systemd unit, consider using the `kill` or `stop` action instead to make use of systemd's restart policy. - **stop**: Stop the container. To remain backwards compatible, **none** is the default action. Signed-off-by: Valentin Rothberg <vrothberg@redhat.com>
* fix podman pod inspect to support multiple podsPaul Holzinger2022-09-08
| | | | | | | | | | | | | | | | | Just like the other inspect commands `podman pod inspect p1 p2` should return the json for both. To correctly implement this we follow the container inspect logic, this allows use to reuse the global inspect command. Note: To not break the existing single pod output format for podman pod inspect I added a pod-legacy inspect type. This is only used to make sure we will print the pod as single json and not an array like for the other commands. We cannot use the pod type since podman inspect --type pod did return an array and we should not break that as well. Fixes #15674 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
* implement podman updateCharlie Doern2022-09-01
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman update allows users to change the cgroup configuration of an existing container using the already defined resource limits flags from podman create/run. The supported flags in crun are: this command is also now supported in the libpod api via the /libpod/containers/<CID>/update endpoint where the resource limits are passed inthe request body and follow the OCI resource spec format –memory –cpus –cpuset-cpus –cpuset-mems –memory-swap –memory-reservation –cpu-shares –cpu-quota –cpu-period –blkio-weight –cpu-rt-period –cpu-rt-runtime -device-read-bps -device-write-bps -device-read-iops -device-write-iops -memory-swappiness -blkio-weight-device resolves #15067 Signed-off-by: Charlie Doern <cdoern@redhat.com>

* podman ssh work, using new c/common interfaceCharlie Doern2022-08-09
| | | | | | | | | | | | | | | | | | | implement new ssh interface into podman this completely redesigns the entire functionality of podman image scp, podman system connection add, and podman --remote. All references to golang.org/x/crypto/ssh have been moved to common as have native ssh/scp execs and the new usage of the sftp package. this PR adds a global flag, --ssh to podman which has two valid inputs `golang` and `native` where golang is the default. Users should not notice any difference in their everyday workflows if they continue using the golang option. UNLESS they have been using an improperly verified ssh key, this will now fail. This is because podman was incorrectly using the ssh callback method to IGNORE the ssh known hosts file which is very insecure and golang tells you not yo use this in production. The native paths allows for immense flexibility, with a new containers.conf field `SSH_CONFIG` that specifies a specific ssh config file to be used in all operations. Else the users ~/.ssh/config file will be used. podman --remote currently only uses the golang path, given its deep interconnection with dialing multiple clients and urls. My goal after this PR is to go back and abstract the idea of podman --remote from golang's dialed clients, as it should not be so intrinsically connected. Overall, this is a v1 of a long process of offering native ssh, and one that covers some good ground with podman system connection add and podman image scp.

* Add support for creating sigstore signatures, and providing passphrasesMiloslav Trmač2022-07-30
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | - Allow creating sigstore signatures via --sign-by-sigstore-private-key . Like existing --sign-by, it does not work remote (in this case because we would have to copy the private key to the server). - Allow passing a passphrase (which is mandatory for sigstore private keys) via --sign-passphrase-file; if it is not provided, prompt interactively. - Also, use that passphrase for --sign-by as well, allowing non-interactive GPG use. (But --sign-passphrase-file can only be used with _one of_ --sign-by and --sign-by-sigstore-private-key.) Note that unlike the existing code, (podman build) does not yet implement sigstore (I'm not sure why it needs to, it seems not to push images?) because Buildah does not expose the feature yet. Also, (podman image sign) was not extended to support sigstore. The test for this follows existing (podman image sign) tests and doesn't work rootless; that could be improved by exposing a registries.d override option. The test for push is getting large; I didn't want to start yet another registry container, but that would be an alternative. In the future, Ginkgo's Ordered/BeforeAll would allow starting a registry once and using it for two tests. Signed-off-by: Miloslav Trmač <mitr@redhat.com>

| * shell completion: fix problems with container path completionPaul Holzinger2022-06-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When you try to complete a path which exists and it is a file the completion logic did not check the parent dir for other matching file names. To fix that we have to check if the current completion is not a dir and use the parent dir in this case. See the updated test for an example why this is required. Also make sure directories are correctly completed, the shell always adds the "/" as suffix to signal the user that this path is a directory. In this case we do not want to automatically add a space. When the path is a regular file we want the space after the suggestion since there is nothing more to complete. This better matches the normal default shell completion. The test were changed to not assume any particular ordering since this is irrelevant for the shell completion script and there is no guarantee about the ordering.

* | compat api: fix regressions from "Swagger refactor/cleanup"Paul Holzinger2022-06-09
|/ | | | | | | | | | | | | | | | | | | | For some reason commit 5b79cf15a022 moved the container create options parsing from cmd/podman/common to pkg/api/handlers. However it did not remove the old code. Unfortunately it moved the code from an outdated version and did not update it before this commit was merged. Therefore a couple of regressions were introduced. I manually compared both versions and found three missing bugfixes. I fixed the network test again that was changed in bce97a3b5dd1. We want bridge as default even as rootless. Sine the test is not run as rootless in CI the regression was not caught. Also the no hosts test never worked since it was missing the import check if the hosts file exists. I don't think we can check for the volume parsing change since this only works on windows/wsl.

| | | | | | | | | | | | | | | | | | | | | | | | | | Add shell completion for paths inside the container or image. Currently podman run IMAGE [TAB] only uses the default shell completion which suggests paths on the host. This is fine for some cases but often the user wants a path which only exists in the image/container. This commits adds support for that. Both podman create/run can now complete the paths from the image, podman cp ctr:... now completes paths from the actual container. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

| * shell completion --format: add help to function with argsPaul Holzinger2022-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | From a template users POV it is not importent when they use a struct field or method. They only notice the difference when the function requires arguments. So lets be nice and let the user know that this method requires arguments via the help text. This is how it now looks like when the completion descriptions are enabled on bash: ``` $ bin/podman ps --format {{.Created.A {{.Created.AddDate (This is a function and requires 3 arguments) {{.Created.After (This is a function and requires 1 argument) {{.Created.Add (This is a function and requires 1 argument) {{.Created.AppendFormat (This is a function and requires 2 arguments) ``` Signed-off-by: Paul Holzinger <pholzing@redhat.com>
| * shell completion --format: support maps and functionsPaul Holzinger2022-05-18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently we only support structs in a template string like this: `{{.var1.test.` -> this meams that test must be a struct field on var1. Now with this var1 and test could also be either a map or function which returns a struct. A actual example: `podman container inspect --format {{.NetworkSettings.Networks.netname.` Now we can complete the struct fileds after netname. Note that this cannot complete map keys since they are empty by default, so it is impossible to get them in the completion logic. Also this fixes a panic with embeeded nil structs Fixes #14223 Signed-off-by: Paul Holzinger <pholzing@redhat.com>
| * shell completion --format: fix embedded struct handlingPaul Holzinger2022-05-18
| | | | | | | | | | | | | | | | | | | | | | | | When a struct is embeeded it is possible that we end up with same names but different types, this results in incorrect completions. The go template logic always preferes the actual field/method name before the one from the embedded one. Thefore the completion logic should do the same. First get all method/fields names from the struct and then only add the field names from the embedded struct when they are not already present in the list.
