* Add support for containers.confDaniel J Walsh2020-03-27

* 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.

* env: don't set "container" envValentin Rothberg2020-03-04
| | | | | | | | Leave setting the "container" variable to consumers of pkg/env. Podman is now hard-setting it to "podman" while "libpod" will set it internally to "libpod" if it's unset. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

* Rework label parsingMatthew Heon2020-02-14
| | | | | | | | | | | | | | | We attempted to share all logic for parsing labels and environment variables, which on the surface makes lots of sense (both are formatted key=value so parsing logic should be identical) but has begun to fall apart now that we have added additional logic to environment variable handling. Environment variables that are unset, for example, are looked up against environment variables set for the process. We don't want this for labels, so we have to split parsing logic.

* container create: relax os/arch checksValentin Rothberg2020-02-11
| | | | | | | | | | Relax the os/arch checks when creating a container and only info-log mismatches instead of erroring out. There are too many images used in the wild which do not set their arch correctly correctly. Erroring out has hit users sufficiently enough to justify relaxing the errors and only log to at least inform the users and image vendors. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>

| * policy for seccomp-profile selectionValentin Rothberg2020-01-09
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement a policy for selecting a seccomp profile. In addition to the default behaviour (default profile unless --security-opt seccomp is set) add a second policy doing a lookup in the image annotation. If the image has the "io.containers.seccomp.profile" set its value will be interpreted as a seccomp profile. The policy can be selected via the new --seccomp-policy CLI flag. Once the containers.conf support is merged into libpod, we can add an option there as well. Note that this feature is marked as experimental and may change in the future.

* signal parsing - better input validationEd Santiago2019-12-26
| | | | | | | | | | | | | | | | | | | | | | The helper function we use for signal name mapping does not check for negative numbers nor invalid (too-high) ones. This can yield unexpected error messages: # podman kill -s -1 foo ERRO[0000] unknown signal "18446744073709551615" This PR introduces a small wrapper for it that: 1) Strips off a leading dash, allowing '-1' or '-HUP' as valid inputs; and 2) Rejects numbers <1 or >64 (SIGRTMAX) Also adds a test suite checking signal handling as well as ensuring that invalid signals are rejected by the command line. Fixes: #4746 Signed-off-by: Ed Santiago <santiago@redhat.com>
* container config: add CreateCommandValentin Rothberg2019-12-13
| | | | | | | | | | | | | | | | | | Store the full command plus arguments of the process the container has been created with. Expose this data as a `Config.CreateCommand` field in the container-inspect data as well. This information can be useful for debugging, as we can find out which command has created the container, and, if being created via the Podman CLI, we know exactly with which flags the container has been created with. The immediate motivation for this change is to use this information for `podman-generate-systemd` to generate systemd-service files that allow for creating new containers (in contrast to only starting existing ones).

* | Split up create config handling of namespaces and securityPeter Hunt2019-11-07
| | | | | | | | | | | | | | | | As it stands, createconfig is a huge struct. This works fine when the only caller is when we create a container with a fully created config. However, if we wish to share code for security and namespace configuration, a single large struct becomes unweildy, as well as difficult to configure with the single createConfigToOCISpec function. This PR breaks up namespace and security configuration into their own structs, with the eventual goal of allowing the namespace/security fields to be configured by the pod create cli, and allow the infra container to share this with the pod's containers.

| | | | | | | | | | | | "init" is a quite common name for the command executed in a container image and Podman ends up using the systemd mode also when not required.

| * Setup a reasonable default for pids-limit 4096Daniel J Walsh2019-10-04
| | | | | | | | | | | | | | | | | | | | | | CRI-O defaults to 1024 for the maximum pids in a container. Podman should have a similar limit. Once we have a containers.conf, we can set the limit in this file, and have it easily customizable. Currently the documentation says that -1 sets pids-limit=max, but -1 fails. This patch allows -1, but also indicates that 0 also sets the max pids limit. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
