* Fix volume handling in podmanDaniel J Walsh2019-02-14
| | | | | | | | | | | | | | | | | | iFix builtin volumes to work with podman volume Currently builtin volumes are not recored in podman volumes when they are created automatically. This patch fixes this. Remove container volumes when requested Currently the --volume option on podman remove does nothing. This will implement the changes needed to remove the volumes if the user requests it. When removing a volume make sure that no container uses the volume.

* 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differs a bit from the applied one when having started the container, which results in displaying a potentially outdated AppArmor profile when inspecting a container.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'.

* | hooks: Add pre-create hooks for runtime-config manipulationW. Trevor King2019-01-08
|/ | | | | | | | | | | | | | | | | | | | | | | There's been a lot of discussion over in [1] about how to support the NVIDIA folks and others who want to be able to create devices (possibly after having loaded kernel modules) and bind userspace libraries into the container. Currently that's happening in the middle of runc's create-time mount handling before the container pivots to its new root directory with runc's incorrectly-timed prestart hook trigger [2]. With this commit, we extend hooks with a 'precreate' stage to allow trusted parties to manipulate the config JSON before calling the runtime's 'create'. I'm recycling the existing Hook schema from pkg/hooks for this, because we'll want Timeout for reliability and When to avoid the expense of fork/exec when a given hook does not need to make config changes [3].

* Fixes to handle /dev/shm correctly.Daniel J Walsh2018-12-24
| | | | | | | | | | | | | | | | | | We had two problems with /dev/shm, first, you mount the container read/only then /dev/shm was mounted read/only. This is a bug a tmpfs directory should be read/write within a read-only container. The second problem is we were ignoring users mounted /dev/shm from the host. If user specified podman run -d -v /dev/shm:/dev/shm ... We were dropping this mount and still using the internal mount. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>
* Containers sharing a netns should share resolv/hostsMatthew Heon2018-12-11
| | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an image config sets config.User [1] to a numeric group (like 1000:1000), but those values do not exist in the container's /etc/group, libpod is currently breaking: $ podman run --rm registry.svc.ci.openshift.org/ci-op-zvml7cd6/pipeline:installer --help error creating temporary passwd file for container 228f6e9943d6f18b93c19644e9b619ec4d459a3e0eb31680e064eeedf6473678: unable to get gid 1000 from group file: no matching entries in group file However, the OCI spec requires converters to copy numeric uid and gid to the runtime config verbatim [2]. With this commit, I'm frontloading the "is groupspec an integer?" check and only bothering with lookup.GetGroup when it was not. I've also removed a few .Mounted checks, which are originally from 00d38cb3 (podman create/run need to load information from the image, 2017-12-18, #110). We don't need a mounted container filesystem to translate integers. And when the lookup code needs to fall back to the mounted root to translate names, it can handle erroring out internally (and looking it over, it seems to do that already).

* | 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>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | My host system runs Fedora Silverblue 29 and I have NetworkManager's `dns=dnsmasq` setting enabled, so my `/etc/resolv.conf` only has `127.0.0.1`. I also run my development podman containers with `--net=host` for various reasons. If we have a host network namespace, there's no reason not to just use the host's nameserver configuration either. This fixes e.g. accessing content on a VPN, and is also faster since the container is using cached DNS. I know this doesn't solve the bigger picture issue of localhost-DNS conflicting with bridged networking, but that's far more involved, probably requiring a DNS proxy in the container. This patch makes my workflow a lot nicer and was easy to write. Signed-off-by: Colin Walters <walters@verbum.org>

This can be used to rollback the container to an early state: $ podman run --tmpfs /tmp --name podman-criu-test -d docker://docker.io/yovfiatbeb/podman-criu-test $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 3 $ podman container checkpoint -R -l $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 4 $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 5 $ podman stop -l $ podman container restore -l $ curl 10.88.64.253:8080/examples/servlets/servlet/HelloWorldExample 4 So after checkpointing the container kept running and was stopped after some time.

* Add support to checkpoint/restore containersAdrian Reber2018-10-03
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | runc uses CRIU to support checkpoint and restore of containers. This brings an initial checkpoint/restore implementation to podman. None of the additional runc flags are yet supported and container migration optimization (pre-copy/post-copy) is also left for the future. The current status is that it is possible to checkpoint and restore a container. I am testing on RHEL-7.x and as the combination of RHEL-7 and CRIU has seccomp troubles I have to create the container without seccomp. With the following steps I am able to checkpoint and restore a container: # podman run --security-opt="seccomp=unconfined" -d registry.fedoraproject.org/f27/httpd # curl -I 10.22.0.78:8080 HTTP/1.1 403 Forbidden # <-- this is actually a good answer # podman container checkpoint <container> # curl -I 10.22.0.78:8080 curl: (7) Failed connect to 10.22.0.78:8080; No route to host # podman container restore <container> # curl -I 10.22.0.78:8080 HTTP/1.1 403 Forbidden I am using CRIU, runc and conmon from git. All required changes for checkpoint/restore support in podman have been merged in the corresponding projects. To have the same IP address in the restored container as before checkpointing, CNI is told which IP address to use. If the saved network configuration cannot be found during restore, the container is restored with a new IP address. For CRIU to restore established TCP connections the IP address of the network namespace used for restore needs to be the same. For TCP connections in the listening state the IP address can change. During restore only one network interface with one IP address is handled correctly. Support to restore containers with more advanced network configuration will be implemented later. v2: * comment typo * print debug messages during cleanup of restore files * use createContainer() instead of createOCIContainer() * introduce helper CheckpointPath() * do not try to restore a container that is paused * use existing helper functions for cleanup * restructure code flow for better readability * do not try to restore if checkpoint/inventory.img is missing * git add checkpoint.go restore.go v3: * move checkpoint/restore under 'podman container' v4: * incorporated changes from latest reviews Signed-off-by: Adrian Reber <areber@redhat.com>
