7 pods, containers and images.

15 Podman (Pod Manager) is a fully featured container engine that is a
16 simple daemonless tool. Podman provides a Docker-CLI comparable com‐
17 mand line that eases the transition from other container engines and
18 allows the management of pods, containers and images. Simply put:
19 alias docker=podman. Most Podman commands can be run as a regular
20 user, without requiring additional privileges.
21 Podman uses Buildah(1) internally to create container images. Both
24 tools share image (not container) storage, hence each can use or manip‐
25 ulate images (but not containers) created by the other.
26 Podman-remote provides a local client interacting with a Podman backend
29 node through a RESTful API tunneled through a ssh connection. In this
30 context, a Podman node is a Linux system with Podman installed on it
31 and the API service activated. Credentials for this session can be
32 passed in using flags, environment variables, or in containers.conf.
33 The containers.conf file is placed under $HOME/.config/containers/con‐
36 tainers.conf on Linux and Mac and %APPDATA%\containers\containers.conf
37 on Windows.
38 podman [GLOBAL OPTIONS]
41
44 --connection=name, -c
45 Remote connection name
46 Overrides environment variable CONTAINER_CONNECTION if set.
49 --help, -h
52 Print usage statement
53 --identity=path
56 Path to ssh identity file. If the identity file has been encrypted,
57 Podman prompts the user for the passphrase. If no identity file is
58 provided and no user is given, Podman defaults to the user running the
59 podman command. Podman prompts for the login password on the remote
60 server.
61 Identity value resolution precedence:
64 - command line value
65 - environment variable CONTAINER_SSHKEY, if CONTAINER_HOST is found
66 - containers.conf
67 --log-level=level
70 Log messages above specified level: debug, info, warn, error (default),
71 fatal or panic
72 --url=value
75 URL to access Podman service (default from containers.conf, rootless
76 "unix:///run/user/$UID/podman/podman.sock" or as root "unix:///run/pod‐
77 man/podman.sock).
78 • CONTAINER_HOST is of the format <schema>://[<user[:<pass‐
81 word>]@]<host>[:<port>][<path>]
82 • CONTAINER_PROXY is of the format
84 <socks5|socks5h>://[<user[:<password>]@]<host>[:<port>]
85 Details:
89 - schema is one of:
90 * ssh (default): a local unix(7) socket on the named host and port,
91 reachable via SSH
92 * tcp: an unencrypted, unauthenticated TCP connection to the named
93 host and port, can work with proxy if CONTAINER_PROXY is set
94 * unix: a local unix(7) socket at the specified path, or the default
95 for the user
96 - user defaults to either root or the current running user (ssh only)
97 - password has no default (ssh only)
98 - host must be provided and is either the IP or name of the machine
99 hosting the Podman service (ssh and tcp)
100 - port defaults to 22 (ssh and tcp)
101 - path defaults to either /run/podman/podman.sock, or
102 /run/user/$UID/podman/podman.sock if running rootless (unix), or must
103 be explicitly specified (ssh)
104 - CONTAINER_PROXY: use proxy (socks5 or socks5h) to access Podman ser‐
105 vice (tcp only)
106 URL value resolution precedence:
109 - command line value
110 - environment variable CONTAINER_HOST
111 - engine.service_destinations table in containers.conf, excluding the
112 /usr/share/containers directory
113 - unix:///run/podman/podman.sock
114 Remote connections use local containers.conf for default.
117 Some example URL values in valid formats:
120 - unix:///run/podman/podman.sock
121 - unix:///run/user/$UID/podman/podman.sock
122 - ssh://notroot@localhost:22/run/user/$UID/podman/podman.sock
123 - ssh://root@localhost:22/run/podman/podman.sock
124 - tcp://localhost:34451
125 - tcp://127.0.0.1:34451
126 --version
129 Print the version
130
133 Podman can set up environment variables from env of [engine] table in
134 containers.conf. These variables can be overridden by passing environ‐
135 ment variables before the podman commands.
136 CONTAINERS_CONF
139 Set default locations of containers.conf file
140 CONTAINER_CONNECTION
143 Set default --connection value to access Podman service.
144 CONTAINER_HOST
147 Set default --url value to access Podman service.
148 CONTAINER_SSHKEY
151 Set default --identity path to ssh key file value used to access Podman
152 service.
153
156 The exit code from podman gives information about why the container
157 failed to run or why it exited. When podman commands exit with a non-
158 zero code, the exit codes follow the chroot standard, see below:
159 125 The error is with podman itself
162 $ podman run --foo busybox; echo $?
164 Error: unknown flag: --foo
165 125
166 126 Executing a contained command and the command cannot be invoked
170 $ podman run busybox /etc; echo $?
172 Error: container_linux.go:346: starting container process caused "exec: \"/etc\": permission denied": OCI runtime error
173 126
174 127 Executing a contained command and the command cannot be found
178 $ podman run busybox foo; echo $?
179 Error: container_linux.go:346: starting container process caused
180 "exec: \"foo\": executable file not found in $PATH": OCI runtime error
181 127
182 Exit code contained command exit code
185 $ podman run busybox /bin/sh -c 'exit 3'; echo $?

305 containers.conf ($HOME/.config/containers/containers.conf)
306 Podman has builtin defaults for command line options. These defaults
309 can be overridden using the containers.conf configuration files.
310 Users can modify defaults by creating the $HOME/.config/containers/con‐
313 tainers.conf file. Podman merges its builtin defaults with the speci‐
314 fied fields from this file, if it exists. Fields specified in the users
315 file override the built-in defaults.
316 Podman uses builtin defaults if no containers.conf file is found.
