-# VyOS as Docker container
-
-VyOS can be run as a Docker container on a Linux host with a compatible kernel.
-
-## Build Container
-
-To build a Docker image you need to have the whole `vyos-build` repository, not
-only a folder with Dockerfile, because some files from this repository are
-required for building.
-
-Docker image with VyOS can be built on Linux host with the next command:
-
-```console
-docker build --compress --file Dockerfile \
-  --tag vyos:version-`date -u +%Y%m%d%H%M%S` \
-  --build-arg BUILD_DATE="`date -u --rfc-3339=seconds`" \
-  --build-arg VYOS_VERSION=version \
-  --build-arg DEBIAN_VERSION=debian \
-  --progress plain ..
-```
-
-Or, if you want to rebuild completely from the scratch (without cache):
-
-```console
-docker build --no-cache --pull --compress --file Dockerfile \
-  --tag vyos:version-`date -u +%Y%m%d%H%M%S` \
-  --build-arg BUILD_DATE="`date -u --rfc-3339=seconds`" \
-  --build-arg VYOS_VERSION=version \
-  --build-arg DEBIAN_VERSION=debian \
-  --progress plain ..
-```
-
-> **_NOTE:_** You must use proper version value for `DEBIAN_VERSION` variable.
-  It can be only `jessie` (for VyOS 1.2) or `buster` (for VyOS 1.3).
-
-## Run Container
-
-Docker container with VyOS can be running with the next command:
-
-```console
-docker run --privileged --detach \
-  --volume /lib/modules:/lib/modules \
-  --name vyos_inside_docker vyos:version
-```
-
-You need to use the `--privileged` flag because the system actively interacts
-with a host kernel to perform routing operations and tune networking options.
-
-**Experimantal:** You can limit access to some system resources with:
-
-```console
-docker run --privileged --detach \
-   --tmpfs /tmp \
-   --tmpfs /run \
-   --tmpfs /run/lock \
-   --volume /lib/modules:/lib/modules:ro \
-   --volume /sys/fs/cgroup:/sys/fs/cgroup:ro \
-   --name vyos_inside_docker vyos:version
-```
-
-### Log into container
-
-To open VyOS CLI, you can use SSH connection to the Docker container or run
-on host:
-
-```console
-docker exec -it vyos_inside_docker su vyos
-```
-
-## Troubleshooting
-
-If in VyOS appears IPv6-related errors, for example, it cannot assign an IPv6
-address for an interface, it is necessary to enable IPv6 support in Docker.
-
-This can be done, by editing `/etc/docker/daemon.json`:
-
-```console
-{
-    "ipv6": true,
-    "fixed-cidr-v6": "fe80::/64"
-}
-```
