|\ | | | | Add the rmi flag to podman-run to delete container image
| * Add the rmi flag to podman-run to delete container imageBoaz Shuster2020-03-03
| | | | | | | | | | | | | | | | | | | | The --rmi flag will delete the container image after its execution unless that image is already been used by another container(s). This is useful when one wants to execute a container once and remove any resources attached to it. Signed-off-by: Boaz Shuster <boaz.shuster.github@gmail.com>
* | consolidate env handling into pkg/envValentin Rothberg2020-03-03

* Add basic deadlock detection for container start/removeMatthew Heon2020-02-24
| | | | | | | | | | | | | | | We can easily tell if we're going to deadlock by comparing lock IDs before actually taking the lock. Add a few checks for this in common places where deadlocks might occur. This does not yet cover pod operations, where detection is more difficult (and costly) due to the number of locks being involved being higher than 2. Also, add some error wrapping on the Podman side, so we can tell people to use `system renumber` when it occurs. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* / podman-generate-systemd --newValentin Rothberg2020-01-09
|/ | | | | | | | | | | | | | | Add a --new flag to podman-generate-systemd to create a new container via podman-run instead of starting an existing container. Creating a new container presents the challenge to find a reverse mapping from a container to the CLI flags it can be created with. We are doing this via `(Container).Config.CreateCommand` field, which includes a copy of the process' command from procFS at creating time. This field may not be useful when the container was not created via the Podman CLI (e.g., via a Python script). Hence, we do not guarantee the correctness of the generated files.

* podman {pod,} rm/stop: add --ignore flagValentin Rothberg2019-11-25
| | | | | | | | | | | | Add an --ignore flag to podman rm and stop. When specified, Podman will ignore "no such {container,pod}" errors that occur when a specified container/pod is not present in the store (anymore). The motivation behind adding this flag is to write more robust systemd services using Podman. A user might have manually decided to remove a container/pod which would lead to a failure during the `ExecStop` directive of a systemd service referencing that container/pod. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* podman rm/stop --cidfileValentin Rothberg2019-11-18
| | | | | | | | | | Add a --cidfile flag to podman rm/stop to pass a container ID via a file. Podman run already provides the functionaly to store the ID in a specified file which we now complete with rm/stop. This allows for a better life-cycle management in systemd services. Note that --cdifile can be specified multiple times to rm/stop. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * Switch to bufio Reader for exec streamsPeter Hunt2019-10-31
| | | | | | | | | | | | | | | | There were many situations that made exec act funky with input. pipes didn't work as expected, as well as sending input before the shell opened. Thinking about it, it seemed as though the issues were because of how os.Stdin buffers (it doesn't). Dropping this input had some weird consequences. Instead, read from os.Stdin as bufio.Reader, allowing the input to buffer before passing it to the container. Signed-off-by: Peter Hunt <pehunt@redhat.com>

* | container start: fix regression when using nameValentin Rothberg2019-10-31
|/ | | | | | | | | | | | | When starting a container by using its name as a reference, we should print the name instead of the ID. We regressed on this behaviour with commit b4124485ae7e which made it into Podman v1.6.2. Kudos to openSUSE testing for catching it. To prevent future regressions, extend the e2e tests to check the printed container name/ID. Reported-by: @sysrich Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * Add support for anonymous volumes to `podman run -v`Matthew Heon2019-10-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previously, when `podman run` encountered a volume mount without separate source and destination (e.g. `-v /run`) we would assume that both were the same - a bind mount of `/run` on the host to `/run` in the container. However, this does not match Docker's behavior - in Docker, this makes an anonymous named volume that will be mounted at `/run`. We already have (more limited) support for these anonymous volumes in the form of image volumes. Extend this support to allow it to be used with user-created volumes coming in from the `-v` flag. This change also affects how named volumes created by the container but given names are treated by `podman run --rm` and `podman rm -v`. Previously, they would be removed with the container in these cases, but this did not match Docker's behaviour. Docker only removed anonymous volumes. With this patch we move to that model as well; `podman run -v testvol:/test` will not have `testvol` survive the container being removed by `podman rm -v`. The sum total of these changes let us turn on volume removal in `--rm` by default. Fixes: #4276 Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Move OCI runtime implementation behind an interfaceMatthew Heon2019-10-10
| | | | | | | | | | | | For future work, we need multiple implementations of the OCI runtime, not just a Conmon-wrapped runtime matching the runc CLI. As part of this, do some refactoring on the interface for exec (move to a struct, not a massive list of arguments). Also, add 'all' support to Kill and Stop (supported by runc and used a bit internally for removing containers). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Update c/image to v4.0.1 and buildah to 1.11.3Miloslav Trmač2019-10-04
| | | | | | | | | | | | | | This requires updating all import paths throughout, and a matching buildah update to interoperate. I can't figure out the reason for go.mod tracking github.com/containers/image v3.0.2+incompatible // indirect ((go mod graph) lists it as a direct dependency of libpod, but (go list -json -m all) lists it as an indirect dependency), but at least looking at the vendor subdirectory, it doesn't seem to be actually used in the built binaries.
