.. cfgcmd:: set container <name>
Set a named 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.
.. cfgcmd:: set container <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> 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> description <text>
Sets the container description
.. cfgcmd:: set container <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> network <networkname>
Attaches user-defined network to a container.
Only one network must be specified and must already exist.
Optionally a specific static IPv4 or IPv6 address can be set for
the container. This address must be within the named network.
.. code-block:: none
set container <name> network <networkname> address <address>
.. note:: The first IP in the container network is reserved by the engine and cannot be used
.. cfgcmd:: set container <name> port <portname> [source | destination ] <portnumber>
Publishes 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
.. cfgcmd:: set container <name> volume <volumename> [source | 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
