* add libpod/configValentin Rothberg2019-10-31
| | | | | | | | | | | | Refactor the `RuntimeConfig` along with related code from libpod into libpod/config. Note that this is a first step of consolidating code into more coherent packages to make the code more maintainable and less prone to regressions on the long runs. Some libpod definitions were moved to `libpod/define` to resolve circular dependencies. Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* bump containers/image to v5.0.0, buildah to v1.11.4Nalin Dahyabhai2019-10-29
| | | | | | | | | Move to containers/image v5 and containers/buildah to v1.11.4. Replace an equality check with a type assertion when checking for a docker.ErrUnauthorizedForCredentials in `podman login`. Signed-off-by: Nalin Dahyabhai <nalin@redhat.com>
* Add ensureState helper for checking container stateMatthew Heon2019-10-28
| | | | | | | | | | | | | | | | We have a lot of checks for container state scattered throughout libpod. Many of these need to ensure the container is in one of a given set of states so an operation may safely proceed. Previously there was no set way of doing this, so we'd use unique boolean logic for each one. Introduce a helper to standardize state checks. Note that this is only intended to replace checks for multiple states. A simple check for one state (ContainerStateRunning, for example) should remain a straight equality, and not use this new helper. Signed-off-by: Matthew Heon <mheon@redhat.com>
* 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.

| * Track if a container is restored from an exported checkpointAdrian Reber2019-06-25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of only tracking that a container is restored from a checkpoint locally in runtime_ctr.go this adds a flag to the Container structure. Upcoming patches to correctly label the root file-system mount-point need also to know if a container is restored from a checkpoint. Instead of passing a parameter around a lot of functions, this adds that information to the Container structure. Signed-off-by: Adrian Reber <areber@redhat.com>

* | remove libpod from mainbaude2019-06-25
|/ | | | | | | | | | | | | the compilation demands of having libpod in main is a burden for the remote client compilations. to combat this, we should move the use of libpod structs, vars, constants, and functions into the adapter code where it will only be compiled by the local client. this should result in cleaner code organization and smaller binaries. it should also help if we ever need to compile the remote client on non-Linux operating systems natively (not cross-compiled). Signed-off-by: baude <bbaude@redhat.com>
* Begin adding support for multiple OCI runtimesMatthew Heon2019-06-19
| | | | | | | | | | | | | Allow Podman containers to request to use a specific OCI runtime if multiple runtimes are configured. This is the first step to properly supporting containers in a multi-runtime environment. The biggest changes are that all OCI runtimes are now initialized when Podman creates its runtime, and containers now use the runtime requested in their configuration (instead of always the default runtime). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Purge all use of easyjson and ffjson in libpodMatthew Heon2019-06-13
| | | | | | | | | We're no longer using either of these JSON libraries, dropped them in favor of jsoniter. We can't completely remove ffjson as c/storage uses it and can't easily migrate, but we can make sure that libpod itself isn't doing anything with them anymore.

* Add support for retry count with --restart flagMatthew Heon2019-05-03
| | | | | | | | | The on-failure restart option supports restarting only a given number of times. To do this, we need one additional field in the DB to track restart count (which conveniently fills a field in Inspect we weren't populating), plus some plumbing logic. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add container restart policy to Libpod & PodmanMatthew Heon2019-05-03
| | | | | | | This initial version does not support restart count, but it works as advertised otherwise. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add a StoppedByUser field to the DBMatthew Heon2019-05-03
| | | | | | | | This field indicates that a container was explciitly stopped by an API call, and did not exit naturally. It's used when implementing restart policy for containers. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Use GetContainer instead of LookupContainer for full IDMatthew Heon2019-04-12
| | | | | | | | | | All IDs in libpod are stored as a full container ID. We can get a container by full ID faster with GetContainer (which directly retrieves) than LookupContainer (which finds a match, then retrieves). No reason to use Lookup when we have full IDs present and available. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

* Drop LocalVolumes from our the databaseMatthew Heon2019-04-04
| | | | | | | | We were never using it. It's actually a potentially quite sizable field (very expensive to decode an array of structs!). Removing it should do no harm. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Switch Libpod over to new explicit named volumesMatthew Heon2019-04-04
| | | | | | | | | | | | | This swaps the previous handling (parse all volume mounts on the container and look for ones that might refer to named volumes) for the new, explicit named volume lists stored per-container. It also deprecates force-removing volumes that are in use. I don't know how we want to handle this yet, but leaving containers that depend on a volume that no longer exists is definitely not correct.

* userns: do not use an intermediate mount namespaceGiuseppe Scrivano2019-03-29
| | | | | | | | | | | | | | We have an issue in the current implementation where the cleanup process is not able to umount the storage as it is running in a separate namespace. Simplify the implementation for user namespaces by not using an intermediate mount namespace. For doing it, we need to relax the permissions on the parent directories and allow browsing them. Containers that are running without a user namespace, will still maintain mode 0700 on their directory. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Remove ulele/deepcopier in favor of JSON deep copyMatthew Heon2019-03-27
| | | | | | | | | | | | | We have a very high performance JSON library that doesn't need to perform code generation. Let's use it instead of our questionably performant, reflection-dependent deep copy library. Most changes because some functions can now return errors. Also converts cmd/podman to use jsoniter, instead of pkg/json, for increased performance. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | integration of healthcheck into create and run as well as inspect. healthcheck enhancements are as follows: * add the following options to create|run so that non-docker images can define healthchecks at the container level. * --healthcheck-command * --healthcheck-retries * --healthcheck-interval * --healthcheck-start-period * podman create|run --healthcheck-command=none disables healthcheck as described by an image. * the healthcheck itself and the healthcheck "history" can now be observed in podman inspect * added the wiring for healthcheck history which logs the health history of the container, the current failed streak attempts, and log entries for the last five attempts which themselves have start and stop times, result, and a 500 character truncated (if needed) log of stderr/stdout.

* Do not unmarshal into c.config.SpecMatthew Heon2019-01-18
| | | | | | | | | | | | | We try to keep c.config immutable, but Go doesn't really agree with me that things other than strings and ints can be immutable, so occasionally things like this slip through. When unmarshalling the OCI spec from disk, do it into a separate struct, to ensure we don't make lasting modifications to the spec in the Container struct (which could affect container restart).

* apparmor: apply default profile at container initializationValentin Rothberg2019-01-09
| | | | | | | | | | | | | | | | | | | Apply the default AppArmor profile at container initialization to cover all possible code paths (i.e., podman-{start,run}) before executing the runtime. This allows moving most of the logic into pkg/apparmor. Also make the loading and application of the default AppArmor profile versio-indepenent by checking for the `libpod-default-` prefix and over-writing the profile in the run-time spec if needed. The intitial run-time spec of the container differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container. To fix that, load the container config from the file system if present and use it to display the data. Fixes: #2107 Signed-off-by: Valentin Rothberg <rothberg@redhat.com>
* Use existing interface to request IP address during restoreAdrian Reber2019-01-09
| | | | | | | | | | | | | | | | | | The initial implementation to request the same IP address for a container during a restore was based on environment variables influencing CNI. With this commit the IP address selection switches to Podman's internal static IP API. This commit does a comment change in libpod/container_easyjson.go to avoid unnecessary re-generation of libpod/container_easyjson.go during build as this fails in CI. The reason for this is that make sees that libpod/container_easyjson.go needs to be re-created. The commit, however, only changes a part of libpod/container.go which is marked as 'ffjson: skip'.

* Rename libpod.Config back to ContainerConfigMatthew Heon2019-01-07

| | | | | | | | | | | | | When sharing a network namespace, containers should also share resolv.conf and /etc/hosts in case a container process made changes to either (for example, if I set up a VPN client in container A and join container B to its network namespace, I expect container B to use the DNS servers from A to ensure it can see everything on the VPN).
