# Docker In Docker with Builx and IPv6

Some times Docker in Docker is require for more organization or one time runs such as build container with Gitlab-ci.

Regular dind is not support buildx and IPv6. This repository aim that these kind a problems.

This dind is require privileged mode.

To enable buildx, set env variable buildx is to yes.  

If main docker is configured with IPv6, dind container has a IPv6 detection system and system try to find and set IPv6.  

You can set IPv6 by manual with  set `ipv6` env variable to your IPv6 block

Before build command start docker service with `/src/start-docker.sh`

Example gitlab-ci.yml from some project.

```yml

docker-build:

    variables:

      buildx: "yes"

    image: ahmetozer/dind:latest

    stage: build

    before_script:

      - /src/start-docker.sh

      - docker login -u "ahmetozer" -p "$dhub"

    script:

      - docker buildx build --platform linux/amd64,linux/arm64,linux/arm --push -t ahmetozer/cors-proxy .

    only:

      - master

```

Overlay layer is more optimized for performance and disk space. So you can run your dind with mounting docker lib path to real ext4 path on disk.

```bash

#   Create directory for your dind containers

mkdir -p /dind/dind1

docker run -it --rm --privileged -v /dind/dind1:/var/lib/docker ahmetozer/dind

```

Example gitlab-runner config.

```toml

concurrent = 1

check_interval = 0

[session_server]

  session_timeout = 1800

  listen_address = "[::]:8093"

[[runners]]

  name = "dind1"

  url = "https://gitlab.com/"

  executor = "docker"
