* | libpod: support for cgroup namespaceGiuseppe Scrivano2019-07-18
|/ | | | | | | | | | | | | | allow a container to run in a new cgroup namespace. When running in a new cgroup namespace, the current cgroup appears to be the root, so that there is no way for the container to access cgroups outside of its own subtree. By default it uses --cgroup=host to keep the previous behavior. To create a new namespace, --cgroup=private must be provided. Signed-off-by: Giuseppe Scrivano <gscrivan@redhat.com>
* Populate inspect with security-opt settingsMatthew Heon2019-07-17
| | | | | | | | We can infer no-new-privileges. For now, manually populate seccomp (can't infer what file we sourced from) and SELinux/Apparmor (hard to tell if they're enabled or not). Signed-off-by: Matthew Heon <mheon@redhat.com>
* Move the HostConfig portion of Inspect inside libpodMatthew Heon2019-07-17
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When we first began writing Podman, we ran into a major issue when implementing Inspect. Libpod deliberately does not tie its internal data structures to Docker, and stores most information about containers encoded within the OCI spec. However, Podman must present a CLI compatible with Docker, which means it must expose all the information in 'docker inspect' - most of which is not contained in the OCI spec or libpod's Config struct. Our solution at the time was the create artifact. We JSON'd the complete CreateConfig (a parsed form of the CLI arguments to 'podman run') and stored it with the container, restoring it when we needed to run commands that required the extra info. Over the past month, I've been looking more at Inspect, and refactored large portions of it into Libpod - generating them from what we know about the OCI config and libpod's (now much expanded, versus previously) container configuration. This path comes close to completing the process, moving the last part of inspect into libpod and removing the need for the create artifact. This improves libpod's compatability with non-Podman containers. We no longer require an arbitrarily-formatted JSON blob to be present to run inspect.

* 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We made changes earlier that empty storage options when setting storage driver explicitly. Unfortunately, this breaks rootless cleanup commands, as they lose the fuse-overlayfs mount program path. Fix this by passing along the storage options to the cleanup process. Also, fix --syslog, which was broken a while ago (probably when we broke up main to add main_remote). Fixes #3326 Signed-off-by: Matthew Heon <mheon@redhat.com>

* When superceding mounts, check for opposite typesMatthew Heon2019-05-21
| | | | | | | | | | | | | | | | | | | When we supercede low-priority mounts and volumes (image volumes, and volumes sourced from --volumes-from) with higher-priority ones (the --volume and --mount flags), we always replaced lower-priority mounts of the same type (e.g. a user mount to /tmp/test1 would supercede a volumes-from mount to the same destination). However, we did not supercede the opposite type - a named volume from image volumes at /tmp/test1 would be allowed to remain and create a conflict, preventing container creation. Solve this by destroying opposite types before merging (we can't do it in the same loop, as then named volumes, which go second, might trample changes made by mounts).

* 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.

| | | | | | | | | | | | | | | | | | This ensures that all tmpfs mounts added by the user, even with the --mount flag, share a few common options (nosuid, noexec, nodev), and options for tmpfs mounts are properly validated to ensure they are correct. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | As part of this, move bind mount option validity parsing and modification (adding e.g. rbind on bind mounts that are missing it), which requires test changes (expected values have changed). Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Fix options for non-bind and non-tmpfs volumesMatthew Heon2019-05-01
| | | | | | | | | | | | | | | | | | We were unconditionally resetting volume mount options for all mount points (and by the looks of things, completely dropping tmpfs mounts), which was causing runc to refuse to run containers and all the tests to consequently fail.

| * Migrate unit tests from cmd/podman into pkg/specMatthew Heon2019-05-01
| | | | | | | | | | | | | | | | | | | | Several changes made in the interface of pkg/spec make interacting with it without a runtime difficult to impossible, so move the existing limited testing from cmd/podman (which mostly tested pkg/spec) into pkg/spec itself where we can call individual functions that don't break things.

| * Migrate to unified volume handling codeMatthew Heon2019-05-01
| | | | | | | | | | | | | | | | | | | | | | | | | | Unify handling for the --volume, --mount, --volumes-from, --tmpfs and --init flags into a single file and set of functions. This will greatly improve readability and maintainability. Further, properly handle superceding and conflicting mounts. Our current patchwork has serious issues when mounts conflict, or when a mount from --volumes-from or an image volume should be overwritten by a user volume or named volume.

| * Remove non-config fields from CreateConfigMatthew Heon2019-05-01
| | | | | | | | | | | | | | | | | | The goal here is to keep only the configuration directly used to build the container in CreateConfig, and scrub temporary state and helpers that we need to generate. We'll keep those internally in MakeContainerConfig. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
| * Add a new function for converting a CreateConfigMatthew Heon2019-05-01
| | | | | | | | | | | | | | | | | | | | | | Right now, there are two major API calls necessary to turn a filled-in CreateConfig into the options and OCI spec necessary to make a libpod Container. I'm intending on refactoring both of these extensively to unify a few things, so make a common frontend to both that will prevent API changes from leaking out of the package.

| | | | | | | | | | | The --read-only-tmpfs option caused podman to mount tmpfs on /run, /tmp, /var/tmp if the container is running int read-only mode. The default is true, so you would need to execute a command like --read-only --read-only-tmpfs=false to turn off this behaviour. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
