* fix compat api privileged and entrypoint codebaude2020-10-01
| | | | | | | | when adding /dev to a privileged container using the compatibility API, we need to make sure we dont pass on devices that are simply symlinks. this was already being done by specgen but not on the compat. side. the entrypoint code that was recently rewritten for the compatibility layer was also failing due to the odd inputs that docker is willing to accept in its json, specifically [] vs "". in the case of the latter, this was being made into a []string with a len of one but no content. this would then be used to prefix the command to run in the container and would fail. For example " ls" vs "ls". Signed-off-by: baude <bbaude@redhat.com>

* Ensure DefaultEnvVariables is used in SpecgenMatthew Heon2020-08-18
| | | | | | | | | | | | When we rewrote Podman's pkg/spec, one of the things that was lost was our use of a set of default environment variables, that ensure all containers have at least $PATH and $TERM set. While we're in the process of re-adding it, change it from a variable to a function, so we can ensure the Join function does not overwrite it and corrupt the defaults.

* move go module to v2Valentin Rothberg2020-07-06
| | | | | | | | | | | | | | | With the advent of Podman 2.0.0 we crossed the magical barrier of go modules. While we were able to continue importing all packages inside of the project, the project could not be vendored anymore from the outside. Move the go module to new major version and change all imports to `github.com/containers/libpod/v2`. The renaming of the imports was done via `gomove` [1].

* add {generate,play} kubeValentin Rothberg2020-05-06
| | | | | | | | | | | | | | | | | | | Add the `podman generate kube` and `podman play kube` command. The code has largely been copied from Podman v1 but restructured to not leak the K8s core API into the (remote) client. Both commands are added in the same commit to allow for enabling the tests at the same time. Move some exports from `cmd/podman/common` to the appropriate places in the backend to avoid circular dependencies. Move definitions of label annotations to `libpod/define` and set the security-opt labels in the frontend to make kube tests pass. Implement rest endpoints, bindings and the tunnel interface.

| * Allow devs to set labels in container images for default capabilities.Daniel J Walsh2020-03-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch allows users to specify the list of capabilities required to run their container image. Setting a image/container label "io.containers.capabilities=setuid,setgid" tells podman that the contained image should work fine with just these two capabilties, instead of running with the default capabilities, podman will launch the container with just these capabilties. If the user or image specified capabilities that are not in the default set, the container will print an error message and will continue to run with the default capabilities.

* Split up create config handling of namespaces and securityPeter Hunt2019-11-07
| | | | | | | | As it stands, createconfig is a huge struct. This works fine when the only caller is when we create a container with a fully created config. However, if we wish to share code for security and namespace configuration, a single large struct becomes unweildy, as well as difficult to configure with the single createConfigToOCISpec function. This PR breaks up namespace and security configuration into their own structs, with the eventual goal of allowing the namespace/security fields to be configured by the pod create cli, and allow the infra container to share this with the pod's containers.

* namespaces: by default create cgroupns on cgroups v2Giuseppe Scrivano2019-11-05
| | | | | | | | | | | | | | | | change the default on cgroups v2 and create a new cgroup namespace. When a cgroup namespace is used, processes inside the namespace are only able to see cgroup paths relative to the cgroup namespace root and not have full visibility on all the cgroups present on the system.

* Setup a reasonable default for pids-limit 4096Daniel J Walsh2019-10-04
| | | | | | | | | | | CRI-O defaults to 1024 for the maximum pids in a container. Podman should have a similar limit. Once we have a containers.conf, we can set the limit in this file, and have it easily customizable. Currently the documentation says that -1 sets pids-limit=max, but -1 fails. This patch allows -1, but also indicates that 0 also sets the max pids limit. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

* Set base mount options for bind mounts from base systemMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | If I mount, say, /usr/bin into my container - I expect to be able to run the executables in that mount. Unconditionally applying noexec would be a bad idea. Before my patches to change mount options and allow exec/dev/suid being set explicitly, we inferred the mount options from where on the base system the mount originated, and the options it had there. Implement the same functionality for the new option handling. There's a lot of performance left on the table here, but I don't know that this is ever going to take enough time to make it worth optimizing. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* Add support for 'exec', 'suid', 'dev' mount flagsMatthew Heon2019-08-28
| | | | | | | | | | | | | | | | | | Previously, we explicitly set noexec/nosuid/nodev on every mount, with no ability to disable them. The 'mount' command on Linux will accept their inverses without complaint, though - 'noexec' is counteracted by 'exec', 'nosuid' by 'suid', etc. Add support for passing these options at the command line to disable our explicit forcing of security options. This also cleans up mount option handling significantly. We are still parsing options in more than one place, which isn't good, but option parsing for bind and tmpfs mounts has been unified.

|/ | | | | | | | | | | | | | 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.

* 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.
