|

The VyOS container implementation is based on `Podman<https://podman.io/>` as
|
||
a deamonless container engine.

|
||
*************
|
||
Configuration
|
||
*************
|
||
|
||
.. cfgcmd:: set container name <name> image
|
||
|
||
Sets the image name in the hub registry
|
||
|
||
.. code-block:: none
|
||
|
||
set container name mysql-server image mysql:8.0
|
||
|
||
If a registry is not specified, Docker.io will be used as the container
|
||
registry unless an alternative registry is specified using
|
||
**set container registry <name>** or the registry is included in the image name
|
||
|
||
.. code-block:: none
|
||
|
||
set container name mysql-server image quay.io/mysql:8.0
|
||
|
||
.. cfgcmd:: set container name <name> allow-host-networks
|
||
|
||
Allow host networking in a container. The network stack of the container is
|
||
not isolated from the host and will use the host IP.
|
||
|
||
The following commands translate to "--net host" when the container
|
||
is created
|
||
|
||
.. note:: **allow-host-networks** cannot be used with **network**
|
||
|
||
.. cfgcmd:: set container name <name> network <networkname>
|
||
|
||
Attaches user-defined network to a container.
|
||
Only one network must be specified and must already exist.
|
||
|
||
.. cfgcmd:: set container name <name> network <networkname> address <address>
|
||
|
||
Optionally set a specific static IPv4 or IPv6 address for the container.
|
||
This address must be within the named network prefix.
|
||
|
||
.. note:: The first IP in the container network is reserved by the engine and cannot be used
|
||
|
||
.. cfgcmd:: set container name <name> description <text>
|
||
|
||
Set a container description
|
||
|
||
.. cfgcmd:: set container name <name> environment <key> value <value>
|
||
|
||
Add custom environment variables.
|
||
Multiple environment variables are allowed.
|
||
The following commands translate to "-e key=value" when the container
|
||
is created.
|
||
|
||
.. code-block:: none
|
||
|
||
set container name mysql-server environment MYSQL_DATABASE value 'zabbix'
|
||
set container name mysql-server environment MYSQL_USER value 'zabbix'
|
||
set container name mysql-server environment MYSQL_PASSWORD value 'zabbix_pwd'
|
||
set container name mysql-server environment MYSQL_ROOT_PASSWORD value 'root_pwd'
|
||
|
||
.. cfgcmd:: set container name <name> port <portname> source <portnumber>
|
||
.. cfgcmd:: set container name <name> port <portname> destination <portnumber>
|
||
.. cfgcmd:: set container name <name> port <portname> protocol <tcp | udp>
|
||
|
||
Publish a port for the container.
|
||
|
||
.. code-block:: none
|
||
|
||
set container name zabbix-web-nginx-mysql port http source 80
|
||
set container name zabbix-web-nginx-mysql port http destination 8080
|
||
set container name zabbix-web-nginx-mysql port http protocol tcp
|
||
|
||
.. cfgcmd:: set container name <name> volume <volumename> source <path>
|
||
.. cfgcmd:: set container name <name> volume <volumename> destination <path>
|
||
|
||
Mount a volume into the container
|
||
|
||
.. code-block:: none
|
||
|
||
set container name coredns volume 'corefile' source /config/coredns/Corefile
|
||
set container name coredns volume 'corefile' destination /etc/Corefile
|
||
|
||
.. cfgcmd:: set container name <name> volume <volumename> mode <ro | rw>
|
||
|
||
Volume is either mounted as rw (read-write - default) or ro (read-only)
|
||
|
||
.. cfgcmd:: set container name <name> restart [no | on-failure | always]
|
||
|
||
Set the restart behavior of the container.
|
||
|
||
- **no**: Do not restart containers on exit
|
||
- **on-failure**: Restart containers when they exit with a non-zero exit code, retrying indefinitely (default)
|
||
- **always**: Restart containers when they exit, regardless of status, retrying indefinitely
|
||
|
||
.. cfgcmd:: set container name <name> memory <MB>
|
||
|
||
Constrain the memory available to the container.
|
||
|
||
Default is 512 MB. Use 0 MB for unlimited memory.
|
||
|
||
.. cfgcmd:: set container name <name> device <devicename> source <path>
|
||
.. cfgcmd:: set container name <name> device <devicename> destination <path>
|
||
|
||
Add a host device to the container.
|
||
|
||
.. cfgcmd:: container name <name> cap-add <text>
|
||
|
||
Set container capabilities or permissions.
|
||
|
||
- **net-admin**: Network operations (interface, firewall, routing tables)
|
||
- **net-bind-service**: Bind a socket to privileged ports (port numbers less than 1024)
|
||
- **net-raw**: Permission to create raw network sockets
|
||
- **setpcap**: Capability sets (from bounded or inherited set)
|
||
- **sys-admin**: Administation operations (quotactl, mount, sethostname, setdomainame)
|
||
- **sys-time**: Permission to set system clock
|
||
|
||
.. cfgcmd:: set container name <name> disable
|
||
|
||
Disable a container.
|
||
|
||
.. cfgcmd:: set container network <networkname>
|
||
|
||
Creates a named container network
|
||
|
||
.. cfgcmd:: set container registry <name>
|
||
|
||
Adds registry to list of unqualified-search-registries. By default, for any

||
image that does not include the registry in the image name, Vyos will use
|
||
docker.io as the container registry.
