* 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).

* Make Inspect's mounts struct accurate to DockerMatthew Heon2019-06-12
| | | | | | | | | | | We were formerly dumping spec.Mount structs, with no care as to whether it was user-generated or not - a relic of the very early days when we didn't know whether a user made a mount or not. Now that we do, match our output to Docker's dedicated mount struct. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We accidentally patched this out trying to enable ns:/path/to/ns This should restore the ability to configure nondefault CNI networks with Podman, by ensuring that they request creation of a network namespace.

* Only remove image volumes when removing containersMatthew Heon2019-02-26
| | | | | | | | | | | | When removing volumes with rm --volumes we want to only remove volumes that were created with the container. Volumes created separately via 'podman volume create' should not be removed. Also ensure that --rm implies volumes will be removed. Fixes #2441 Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Validate VolumePath against DB configurationMatthew Heon2019-02-26

* When location of c/storage root changes, set VolumePathMatthew Heon2019-02-26
| | | | | | | | | | | | | | | We want named volumes to be created in a subdirectory of the c/storage graph root, the same as the libpod root directory is now. As such, we need to adjust its location when the graph root changes location. Also, make a change to how we set the default. There's no need to explicitly set it every time we initialize via an option - that might conflict with WithStorageConfig setting it based on graph root changes. Instead, just initialize it in the default config like our other settings. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Fix up handling of user defined network namespacesDaniel J Walsh2019-02-23

* Do not make renumber shut down the runtimeMatthew Heon2019-02-21
| | | | | | | | | | | | | | | The original intent behind the requirement was to ensure that, if two SHM lock structs were open at the same time, we should not make such a runtime available to the user, and should clean it up instead. It turns out that we don't even need to open a second SHM lock struct - if we get an error mapping the first one due to a lock count mismatch, we can just delete it, and it cleans itself up when it errors. So there's no reason not to return a valid runtime. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Move RenumberLocks into runtime initMatthew Heon2019-02-21
| | | | | | | | | | | | | | | | | | We can't do renumbering after init - we need to open a potentially invalid locks file (too many/too few locks), and then potentially delete the old locks and make new ones. We need to be in init to bypass the checks that would otherwise make this impossible. This leaves us with two choices: make RenumberLocks a separate entrypoint from NewRuntime, duplicating a lot of configuration load code (we need to know where the locks live, how many there are, etc) - or modify NewRuntime to allow renumbering during it. Previous experience says the first is not really a viable option and produces massive code bloat, so the second it is. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | we can define multiple OCI runtimes that can be chosen with --runtime. in libpod.conf is possible to specify them with: [runtimes] foo = [ "/usr/bin/foo", "/usr/sbin/foo", ] bar = [ "/usr/bin/foo", "/usr/sbin/foo", ] If the argument to --runtime is an absolute path then it is used directly without any lookup in the configuration.

| * Move rootless storage config into libpodMatthew Heon2018-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous commits ensured that we would use database-configured paths if not explicitly overridden. However, our runtime generation did unconditionally override storage config, which made this useless. Move rootless storage configuration setup to libpod, and change storage setup so we only override if a setting is explicitly set, so we can still override what we want.

| * Add a struct indicating if some Runtime fields were setMatthew Heon2018-12-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | To configure runtime fields from the database, we need to know whether they were explicitly overwritten by the user (we don't want to overwrite anything that was explicitly set). Store a struct containing whether the variables we'll grab from the DB were explicitly set by the user so we know what we can and can't overwrite. This determines whether libpod runtime and static dirs were set via config file in a horribly hackish way (double TOML decode), but I can't think of a better way, and it shouldn't be that expensive as the libpod config is tiny.

* | libpod/container_internal: Deprecate implicit hook directoriesW. Trevor King2018-12-03

The reason this was caught is people > are trying to get hooks to work with CoreOS. You are not allowed to > write to /usr/share... on CoreOS, so they wanted podman to also look > at /etc, where users and third parties can write. But we'd also been disabling hooks completely for rootless users. And even for root users, the override logic was tricky when folks actually had content in both directories. For example, if you wanted to disable a hook from the default directory, you'd have to add a no-op hook to the override directory. Also, the previous implementation failed to handle the case where there hooks defined in the override directory but the default directory did not exist: $ podman version Version: 0.11.2-dev Go Version: go1.10.3 Git Commit: "6df7409cb5a41c710164c42ed35e33b28f3f7214" Built: Sun Dec 2 21:30:06 2018 OS/Arch: linux/amd64 $ ls -l /etc/containers/oci/hooks.d/test.json -rw-r--r--. 1 root root 184 Dec 2 16:27 /etc/containers/oci/hooks.d/test.json $ podman --log-level=debug run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T21:31:19-08:00" level=debug msg="reading hooks from /usr/share/containers/oci/hooks.d" time="2018-12-02T21:31:19-08:00" level=warning msg="failed to load hooks: {}%!(EXTRA *os.PathError=open /usr/share/containers/oci/hooks.d: no such file or directory)" With this commit: $ podman --log-level=debug run --rm docker.io/library/alpine echo 'successful container' 2>&1 | grep -i hook time="2018-12-02T21:33:07-08:00" level=debug msg="reading hooks from /usr/share/containers/oci/hooks.d" time="2018-12-02T21:33:07-08:00" level=debug msg="reading hooks from /etc/containers/oci/hooks.d" time="2018-12-02T21:33:07-08:00" level=debug msg="added hook /etc/containers/oci/hooks.d/test.json" time="2018-12-02T21:33:07-08:00" level=debug msg="hook test.json matched; adding to stages [prestart]" time="2018-12-02T21:33:07-08:00" level=warning msg="implicit hook directories are deprecated; set --hooks-dir="/etc/containers/oci/hooks.d" explicitly to continue to load hooks from this directory" time="2018-12-02T21:33:07-08:00" level=error msg="container create failed: container_linux.go:336: starting container process caused "process_linux.go:399: container init caused \"process_linux.go:382: running prestart hook 0 caused \\\"error running hook: exit status 1, stdout: , stderr: oh, noes!\\\\n\\\"\"" (I'd setup the hook to error out). You can see that it's silenly ignoring the ENOENT for /usr/share/containers/oci/hooks.d and continuing on to load hooks from /etc/containers/oci/hooks.d. When it loads the hook, it also logs a warning-level message suggesting that callers explicitly configure their hook directories. That will help consumers migrate, so we can drop the implicit hook directories in some future release. When folks *do* explicitly configure hook directories (via the newly-public --hooks-dir and hooks_dir options), we error out if they're missing: $ podman --hooks-dir /does/not/exist run --rm docker.io/library/alpine echo 'successful container' error setting up OCI Hooks: open /does/not/exist: no such file or directory I've dropped the trailing "path" from the old, hidden --hooks-dir-path and hooks_dir_path because I think "dir(ectory)" is already enough context for "we expect a path argument". I consider this name change non-breaking because the old forms were undocumented. Coming back to rootless users, I've enabled hooks now. I expect they were previously disabled because users had no way to avoid /usr/share/containers/oci/hooks.d which might contain hooks that required root permissions. But now rootless users will have to explicitly configure hook directories, and since their default config is from ~/.config/containers/libpod.conf, it's a misconfiguration if it contains hooks_dir entries which point at directories with hooks that require root access. We error out so they can fix their libpod.conf. [1]: https://github.com/containers/libpod/pull/1487#discussion_r218149355 Signed-off-by: W. Trevor King <wking@tremily.us>
