* Fix stuttersDaniel J Walsh2022-09-10
| | | | | | | | | | | | | | Podman adds an Error: to every error message. So starting an error message with "error" ends up being reported to the user as Error: error ... This patch removes the stutter. Also ioutil.ReadFile errors report the Path, so wrapping the err message with the path causes a stutter. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* 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>
* 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>

* Docker-compose disable healthcheck properly handledJake Correnti2022-07-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, if a container had healthchecks disabled in the docker-compose.yml file and the user did a `podman inspect <container>`, they would have an incorrect output: ``` "Healthcheck":{ "Test":[ "CMD-SHELL", "NONE" ], "Interval":30000000000, "Timeout":30000000000, "Retries":3 } ``` After a quick change, the correct output is now the result: ``` "Healthcheck":{ "Test":[ "NONE" ] } ``` Additionally, I extracted the hard-coded strings that were used for comparisons into constants in `libpod/define` to prevent a similar issue from recurring.

* | Podman no-new-privileges formatNiall Crowe2022-05-30
|/ | | | | | | | | | | | In docker, the format of no-new-privileges is "no-new-privileges:true". However, for Podman all that's required is "no-new-privileges", leading to issues when attempting to use features desgined for docker in podman. Adding support for the ":" format to be used along with the "=" format, depedning on which one is entered by the user. fixes #14133 Signed-off-by: Niall Crowe <nicrowe@redhat.com>
* enable gocritic linterPaul Holzinger2022-04-26
| | | | | | | | | | | | | | | | | | | | | | The linter ensures a common code style. - use switch/case instead of else if - use if instead of switch/case for single case statement - add space between comment and text - detect the use of defer with os.Exit() - use short form var += "..." instead of var = var + "..." - detect problems with append() ``` newSlice := append(orgSlice, val) ``` This could lead to nasty bugs because the orgSlice will be changed in place if it has enough capacity too hold the new elements. Thus we newSlice might not be a copy. Of course most of the changes are just cosmetic and do not cause any logic errors but I think it is a good idea to enforce a common style. This should help maintainability. Signed-off-by: Paul Holzinger <pholzing@redhat.com>

* Implement Podman Container Clonecdoern2022-02-20
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | podman container clone takes the id of an existing continer and creates a specgen from the given container's config recreating all proper namespaces and overriding spec options like resource limits and the container name if given in the cli options this command utilizes the common function DefineCreateFlags meaning that we can funnel as many create options as we want into clone over time allowing the user to clone with as much or as little of the original config as they want. container clone takes a second argument which is a new name and a third argument which is an image name to use instead of the original container's the current supported flags are: --destroy (remove the original container) --name (new ctr name) --cpus (sets cpu period and quota) --cpuset-cpus --cpu-period --cpu-rt-period --cpu-rt-runtime --cpu-shares --cpuset-mems --memory --run resolves #10875 Signed-off-by: cdoern <cdoern@redhat.com> Signed-off-by: cdoern <cbdoer23@g.holycross.edu> Signed-off-by: cdoern <cdoern@redhat.com>

| | | | | | | | | | | | | `--blkio-weight-device` is not fully implemented and this causes an unexpected panic when specified because an entry is put into an uninitialized map at parsing. This fix implements the `--blkio-weight-device` and adds a system test. When creating a spec generator on a client, a major number and a minor number of a device cannot be set. So, these numbers are inspected on a server and set to a runtime spec. Signed-off-by: Hironori Shiina <shiina.hironori@jp.fujitsu.com>
