* 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>
* Add support for launching containers without CGroupsMatthew Heon2019-09-10
| | | | | | | This is mostly used with Systemd, which really wants to manage CGroups itself when managing containers via unit file. Signed-off-by: Matthew Heon <matthew.heon@pm.me>
* cli-flags: use a consistent format for <size><unit>Marco Vedovati2019-09-05
| | | | | | | | Use a consistent format for description of the <size><unit> flags. Also, avoid backticks for /dev/shm, as that's interpreted as the format by the flag parsing lib. Signed-off-by: Marco Vedovati <mvedovati@suse.com>
* add --pull flag for podman create&runQi Wang2019-08-09
| | | | | | | | | | | Requirement from https://github.com/containers/libpod/issues/3575#issuecomment-512238393 Added --pull for podman create and pull to match the newly added flag in docker CLI. `missing`: default value, podman will pull the image if it does not exist in the local. `always`: podman will always pull the image. `never`: podman will never pull the image.

* 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>
* Make the healthcheck flags compatible with Docker CLIHunor Csomortáni2019-07-16
| | | | | | | | | | | | Docker CLI calls the healthcheck flags "--health-*", instead of "--healthcheck-*". Introduce the former, in order to keep compatibility, and alias the later, in order to avoid breaking current usage. Change "--healthcheck-*" to "--health-*" in the docs and tests. Signed-off-by: Hunor Csomortáni <csomh@redhat.com>
* Add support for -env-hostDaniel J Walsh2019-07-11
| | | | | | | | | | This flag passes the host environment into the container. The basic idea is to leak all environment variables from the host into the container. Environment variables from the image, and passed in via --env and --env-file will override the host environment. Signed-off-by: Daniel J Walsh <dwalsh@redhat.com>

| | | | | | | | | | | | | | | | | | With StringSlice, we're seeing individual options added and parsed separately, so `tmpfs:nosuid,nodev` turns into three tmpfs mounts passed into pkg/sec (tmpfs:, nosuid, nodev).

* | 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).

* Add --read-only-tmpfs optionsDaniel J Walsh2019-04-26
| | | | | | | | | | | 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>

| | | | | | | | | | | | | We have a very high performance JSON library that doesn't need to perform code generation. Let's use it instead of our questionably performant, reflection-dependent deep copy library. Most changes because some functions can now return errors. Also converts cmd/podman to use jsoniter, instead of pkg/json, for increased performance. Signed-off-by: Matthew Heon <matthew.heon@pm.me>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Remove hardcoded '(default: true)' strings from bool flags, and '(default this-or-that)' from string flags. First because it's unmaintainable duplication that would cause confusion should someone ever change the default and not notice the message. Second, because cobra[1] already prints '(default XXXX)' for all options with non-false non-nil default. So in each of these cases, current podman help behavior is: $ podman login --help ... --tls-verify Require HTTPS ... (default: true) (default true) This PR eliminates that duplication. [1] actually spf13/pflag/flag.go The only nontrivial one of these is start.go, where the default for sigProxy depends on the --attach flag. Solution: change the command-line default to false, and implement the new conditional default in logic. Bonus: removed unnecessary check, because now if sigProxy is set without --attach, we can guarantee that it was done by the user. But please pay close scrutiny to this particular section in case there's something I missed. Signed-off-by: Ed Santiago <santiago@redhat.com>

* | podman-commands script: refactorEd Santiago2019-02-28
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make more general-purpose: instead of hardcoding a list of known subcommands, and duplicating sed pipelines for each, rely on 'podman help' itself to tell us which podman commands have subcommands; and examine each in turn. Should there ever be new subcommands, this will identify and test them. A special case is needed for 'podman image trust', whose documentation format doesn't match the others. The change to `common.go` fixes an inconsistency: the Usage message for commands with subcommands had an unnecessary blank line, making it harder to parse automatically. This simply produces consistent Usage messages for all podman commands. This script will not pass until #2480 is merged. After that, the goal is to add this as a CI hook.

| | | | | | | | | | | | | | | | | | | Add support for executing an init binary as PID 1 in a container to forward signals and reap processes. When the `--init` flag is set for podman-create or podman-run, the init binary is bind-mounted to `/dev/init` in the container and "/dev/init --" is prepended to the container's command. The default base path of the container-init binary is `/usr/libexec/podman` while the default binary is catatonit [1]. This default can be changed permanently via the `init_path` field in the `libpod.conf` configuration file (which is recommended for packaging) or temporarily via the `--init-path` flag of podman-create and podman-run.
