* catch command-not-found errorsValentin Rothberg2018-08-31
| | | | | | | | | | | | | | | | | | | | Add a special handler to catch errors caused by specifying unknown commands to Podman. This allows printing a more helpful error message. ``` $ podman Command "123123" not found. See `podman --help`. $ podman pod 123123 Command "123123" not found. See `podman pod --help`. ``` Signed-off-by: Valentin Rothberg <vrothberg@suse.com> Closes: #1379 Approved by: rhatdan
* don't print help message for usage errorsValentin Rothberg2018-08-31
| | | | | | | | | | | | | | | | | Don't print potentially verbose help messages in case of usage errors, but print only the usage error followed by a pointer to the command's help. This aligns with Docker. ``` $ podman run -h flag needs an argument: -h See 'podman run --help'. ``` Signed-off-by: Valentin Rothberg <vrothberg@suse.com> Closes: #1379 Approved by: rhatdan
* Vendor in latest containers/storage and containers/imageDaniel J Walsh2018-08-31
| | | | | | | | | | | | | Update container/image to address a commit error when copying layers and metadata. This change may require users to recreate containers. container/storage added some new lock protection to prevent possible deadlock and data corruption.

* varlink: fix --timeout usageGiuseppe Scrivano2018-08-30
| | | | | | | | | | | | | | | The varlink usage help looks like: --timeout value, -t value time until the varlink session expires in milliseconds. default is 1 second; 0 means no timeout.

* Resolve /etc/resolv.conf before readingbaude2018-08-28
| | | | | | | | | | | | | | | | | In some cases, /etc/resolv.conf can be a symlink to something like /run/systemd/resolve/resolv.conf. We currently check for that file and if it exists, use it instead of /etc/resolv.conf. However, we are no seeing cases where the systemd resolv.conf exists but /etc/resolv.conf is NOT a symlink. Therefore, we now obtain the endpoint for /etc/resolv.conf whether it is a symlink or not. That endpoint is now what is read to generate a container's resolv.conf.

* document `--rm` semanticsValentin Rothberg2018-08-28
| | | | | | | | | | | | | | The `--rm` flag will only cause a container to be removed when it has been created and started successfully. Otherwise, it will not be removed to allow the container to be inspected and to analyze the root cause of the failure. Document those semantics more clearly in the manpages to avoid confusion for users. Fixes: #1359 Signed-off-by: Valentin Rothberg <vrothberg@suse.com> Closes: #1362 Approved by: rhatdan

* Test RPM build and install for regressionsbaude2018-08-28
| | | | | | | | | | | | On Fedora and now Centos (added), we build RPMs based on the spec in contrib/spec to make sure we protect against regressions when creating RPMs. Once the RPM is built, we then test actually installing the RPM to ensure that no deps are missing for install.

* Ensure return errors match API docsbaude2018-08-28

* Fix handling of multiple filters in podman psMatthew Heon2018-08-27
| | | | | | | | | | | | | Docker expects multiple filters to be passed with multiple uses of the --filter flag (e.g. --filter=label=a=b --filter=label=c=d) and not a single comma-separated list of filters as we expected. Convert to the Docker format, and make some small cleanups to our handling of filters along the way. Signed-off-by: Matthew Heon <matthew.heon@gmail.com> Closes: #1345 Approved by: umohnani8

* rootless: exec handle processes that create an user namespaceGiuseppe Scrivano2018-08-26
| | | | | | | | | | | | | | Manage the case where the main process of the container creates and joins a new user namespace.

* rootless: fix execGiuseppe Scrivano2018-08-26
| | | | | | | | | | | | | | | | | | | | | We cannot re-exec into a new user namespace to gain privileges and access an existing as the new namespace is not the owner of the existing container. "unshare" is used to join the user namespace of the target container. The current implementation assumes that the main process of the container didn't create a new user namespace. Since in the setup phase we are not running with euid=0, we must skip the setup for containers/storage.
