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 is placed under $HOME/.config/containers/containers.conf on Linux and Mac and
%APPDATA%\containers\containers.conf on Windows.
podman [GLOBAL OPTIONS]
GLOBAL OPTIONS
--connection=name, -c
Remote connection name
Overrides environment variable CONTAINER_CONNECTION if set.
--help, -h
Print usage statement
--identity=path
Path to ssh identity file. If the identity file has been encrypted, Podman prompts the user for the
passphrase. If no identity file is provided and no user is given, Podman defaults to the user running
the podman command. Podman prompts for the login password on the remote server.
Identity value resolution precedence:
- command line value
- environment variable CONTAINER_SSHKEY, if CONTAINER_HOST is found
- containers.conf
--log-level=level
Log messages above specified level: debug, info, warn, error (default), fatal or panic
--url=value
URL to access Podman service (default from containers.conf, rootless
"unix:///run/user/$UID/podman/podman.sock" or as root "unix:///run/podman/podman.sock).
• CONTAINER_HOST is of the format <schema>://[<user[:<password>]@]<host>[:<port>][<path>]
• CONTAINER_PROXY is of the format <socks5|socks5h>://[<user[:<password>]@]<host>[:<port>]
Details:
- schema is one of:
* ssh (default): a local unix(7) socket on the named host and port, reachable via SSH
* tcp: an unencrypted, unauthenticated TCP connection to the named host and port, can work with proxy
if CONTAINER_PROXY is set
* unix: a local unix(7) socket at the specified path, or the default for the user
- user defaults to either root or the current running user (ssh only)
- password has no default (ssh only)
- host must be provided and is either the IP or name of the machine hosting the Podman service (ssh and
tcp)
- port defaults to 22 (ssh and tcp)
- path defaults to either /run/podman/podman.sock, or /run/user/$UID/podman/podman.sock if running
rootless (unix), or must be explicitly specified (ssh)
- CONTAINER_PROXY: use proxy (socks5 or socks5h) to access Podman service (tcp only)
URL value resolution precedence:
- command line value
- environment variable CONTAINER_HOST
- engine.service_destinations table in containers.conf, excluding the /usr/share/containers directory
- unix:///run/podman/podman.sock
Remote connections use local containers.conf for default.
Some example URL values in valid formats:
- unix:///run/podman/podman.sock
- unix:///run/user/$UID/podman/podman.sock
- ssh://notroot@localhost:22/run/user/$UID/podman/podman.sock
- ssh://root@localhost:22/run/podman/podman.sock
- tcp://localhost:34451
- tcp://127.0.0.1:34451
--version

Environment Variables
Podman can set up environment variables from env of [engine] table in containers.conf. These variables
can be overridden by passing environment variables before the podman commands.
CONTAINERS_CONF
Set default locations of containers.conf file
CONTAINER_CONNECTION
Set default --connection value to access Podman service.
CONTAINER_HOST
Set default --url value to access Podman service.
CONTAINER_SSHKEY
Set default --identity path to ssh key file value used to access Podman service.
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 $?

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.
