## NAME
 | 
						|
podman-remote - A remote CLI for Podman: A Simple management tool for pods, containers and images.
 | 
						|
 | 
						|
## SYNOPSIS
 | 
						|
**podman-remote** [*options*] *command*
 | 
						|
 | 
						|
## DESCRIPTION
 | 
						|
Podman (Pod Manager) is a fully featured container engine that is a simple daemonless tool.
 | 
						|
Podman provides a Docker-CLI comparable command line that eases the transition from other
 | 
						|
container engines and allows the management of pods, containers and images.  Simply put: `alias docker=podman`.
 | 
						|
Most Podman commands can be run as a regular user, without requiring additional
 | 
						|
privileges.
 | 
						|
 | 
						|
Podman uses Buildah(1) internally to create container images. Both tools share image
 | 
						|
(not container) storage, hence each can use or manipulate images (but not containers)
 | 
						|
created by the other.
 | 
						|
 | 
						|
Podman-remote provides a local client interacting with a Podman backend node through a RESTful API tunneled through a ssh connection. In this context, a Podman node is a Linux system with Podman installed on it and the API service activated. Credentials for this session can be passed in using flags, environment variables, or in `containers.conf`.
 | 
						|
 | 
						|
The `containers.conf` file should be placed under `$HOME/.config/containers/containers.conf` on Linux and Mac and `%APPDATA%\containers\containers.conf` on Windows.
 | 
						|
 | 
						|
**podman [GLOBAL OPTIONS]**
 | 
						|
 | 
						|
## GLOBAL OPTIONS
 | 
						|
 | 
						|
**--connection**=*name*, **-c**
 | 
						|
 | 
						|
Remote connection name
 | 
						|
 | 
						|
**--help**, **-h**
 | 
						|
 | 
						|
Print usage statement
 | 
						|
 | 
						|
**--identity**=*path*
 | 
						|
 | 
						|
Path to ssh identity file. If the identity file has been encrypted, Podman prompts the user for the passphrase.
 | 
						|
If no identity file is provided and no user is given, Podman defaults to the user running the podman command.
 | 
						|
Podman prompts for the login password on the remote server.
 | 
						|
 | 
						|
Identity value resolution precedence:
 | 
						|
 - command line value
 | 
						|
 - environment variable `CONTAINER_SSHKEY`, if `CONTAINER_HOST` is found
 | 
						|
 - `containers.conf`
 | 
						|
 | 
						|
**--log-level**=*level*
 | 
						|
 | 
						|
Log messages above specified level: debug, info, warn, error (default), fatal or panic
 | 
						|
 | 
						|
**--url**=*value*
 | 
						|
 | 
						|
URL to access Podman service (default from `containers.conf`, rootless "unix://run/user/$UID/podman/podman.sock" or as root "unix://run/podman/podman.sock).
 | 
						|
 | 
						|
 - `CONTAINER_HOST` is of the format `<schema>://[<user[:<password>]@]<host>[:<port>][<path>]`
 | 
						|
 | 
						|
Details:
 | 
						|
 - `user` will default to either `root` or current running user
 | 
						|
 - `password` has no default
 | 
						|
 - `host` must be provided and is either the IP or name of the machine hosting the Podman service
 | 
						|
 - `port` defaults to 22
 | 
						|
 - `path` defaults to either `/run/podman/podman.sock`, or `/run/user/<uid>/podman/podman.sock` if running rootless.
 | 
						|
 | 
						|
URL value resolution precedence:
 | 
						|
 - command line value
 | 
						|
 - environment variable `CONTAINER_HOST`
 | 
						|
 - `containers.conf`
 | 
						|
 - `unix://run/podman/podman.sock`
 | 
						|
 | 
						|
**--version**
 | 
						|
 | 
						|
Print the version
 | 
						|
 | 
						|
## Exit Status
 | 
						|
 | 
						|
The exit code from `podman` gives information about why the container
 | 
						|
failed to run or why it exited.  When `podman` commands exit with a non-zero code,
 | 
						|
the exit codes follow the `chroot` standard, see below:
 | 
						|
 | 
						|
  **125** The error is with podman itself
 | 
						|
 | 
						|
    $ podman run --foo busybox; echo $?
 | 
						|
    Error: unknown flag: --foo
 | 
						|
    125
 | 
						|
 | 
						|
  **126** Executing a _contained command_ and the _command_ cannot be invoked
 | 
						|
 | 
						|
    $ podman run busybox /etc; echo $?
 | 
						|
    Error: container_linux.go:346: starting container process caused "exec: \"/etc\": permission denied": OCI runtime error
 | 
						|
    126
 | 
						|
 | 
						|
  **127** Executing a _contained command_ and the _command_ cannot be found
 | 
						|
    $ podman run busybox foo; echo $?
 | 
						|
    Error: container_linux.go:346: starting container process caused "exec: \"foo\": executable file not found in $PATH": OCI runtime error
 | 
						|
    127
 | 
						|
 | 
						|
  **Exit code** _contained command_ exit code
 | 
						|
 | 
						|
    $ podman run busybox /bin/sh -c 'exit 3'; echo $?
 | 
						|
    3

## FILES
 | 
						|
 | 
						|
**containers.conf** (`$HOME/.config/containers/containers.conf`)
 | 
						|
 | 
						|
Podman has builtin defaults for command line options. These defaults can be overridden using the containers.conf configuration files.
 | 
						|
 | 
						|
Users can modify defaults by creating the `$HOME/.config/containers/containers.conf` file. Podman merges its builtin defaults with the specified fields from this file, if it exists. Fields specified in the users file override the built-in defaults.
 | 
						|
 | 
						|
Podman uses builtin defaults if no containers.conf file is found.
 | 
						|
