## NAME
|
|
podman\-system\-service - Run an API service
|
|
|
|
## SYNOPSIS
|
|
**podman system service** [*options*]
|
|
|
|
## DESCRIPTION
|
|
The **podman system service** command creates a listening service that will answer API calls for Podman. You may
|
|
optionally provide an endpoint for the API in URI form. For example, *unix:///tmp/foobar.sock* or *tcp://localhost:8080*.
|
|
If no endpoint is provided, defaults will be used. The default endpoint for a rootful
|
|
service is *unix:///run/podman/podman.sock* and rootless is *unix://$XDG_RUNTIME_DIR/podman/podman.sock* (for
|
|
example *unix:///run/user/1000/podman/podman.sock*)
|
|
|
|
To access the API service inside a container:
|
|
- mount the socket as a volume
|
|
- run the container with `--security-opt label=disable`
|
|
|
|
The REST API provided by **podman system service** is split into two parts: a compatibility layer offering support for the Docker v1.40 API, and a Podman-native Libpod layer.
|
|
Documentation for the latter is available at *https://docs.podman.io/en/latest/_static/api.html*.
|
|
Both APIs are versioned, but the server will not reject requests with an unsupported version set.
|
|
|
|
Please note that the API grants full access to Podman's capabilities, and as such should be treated as allowing arbitrary code execution as the user running the API.
|
|
As such, we strongly recommend against making the API socket available via the network.
|
|
The default configuration (a Unix socket with permissions set to only allow the user running Podman) is the most secure way of running the API.
|
|
|
|
Note: The default systemd unit files (system and user) change the log-level option to *info* from *error*. This change provides additional information on each API call.
|
|
|
|
## OPTIONS
|
|
|
|
#### **--cors**
|
|
|
|
CORS headers to inject to the HTTP response. The default value is empty string which disables CORS headers.
|
|
|
|
#### **--help**, **-h**
|
|
|
|
Print usage statement.
|
|
|
|
#### **--time**, **-t**
|
|
|
|
The time until the session expires in _seconds_. The default is 5
|
|
seconds. A value of `0` means no timeout, therefore the session will not expire.
|
|
|
|
The default timeout can be changed via the `service_timeout=VALUE` field in containers.conf.
|
|
See **[containers.conf(5)](https://github.com/containers/common/blob/master/docs/containers.conf.5.md)** for more information.
|
|
|
|
## EXAMPLES
|
|
|
|
Run an API listening for 5 seconds using the default socket.
|
|
```
|
|
podman system service --time 5
|
|
```
