Can docker work inside linux container?

Question

Koding is a collaborative programming environment that creates a virtual machine for multiple users for collaborative software development. They use Linux containers to virtualize machines. I can not install docker on it:

Can anyone suggest a workaround for installing docker?

Answer 1

Yes it is possible. However, you cannot have an aufs section nested in aufs. You need to connect another system or use a different backend.

You can see the file docker file and hack/dind. For this you need privileged mode.

- make shell , docker:)

Answer 2

, Docker Linux.

docker lxc lxc lxc.

, LXC:

1. , lxc.aa_profile = lxc-container-default-with-nesting ( , lxc.aa_profile = unconfined) config LXC, , apparmor. ( ) /etc/apparmor.d/lxc.

2. lxc . , , Ubuntu, apt-get install lxc.

3. , docker --exec-driver=lxc. , docker -d --exec-driver=lxc. Ubuntu, , /etc/default/docker , :

DOCKER_OPTS="--exec-driver"

: https://github.com/docker/docker/issues/6783

:

• apparmor Kern .
• docker -d... , .

. , LXC apparmor Koding, , , , LXC, , , ( ).

- .

.

docker run -i -t --privileged -v /var/lib/docker ubuntu bash
apt-get update && apt-get install -y docker.io
service docker.io start
ln -s /usr/bin/docker.io /usr/local/bin/docker
docker run -i -t ubuntu bash

.

:

• --privileged .
• -v /var/lib/docker, , .
• ln -s /usr/bin/docker.io /usr/local/bin/docker , docker docker.io

.

docker run -privileged -t -i jpetazzo/dind

Answer 5

You can do this inside Terminal.com.

Just launch the terminal and run it: https://blog.terminal.com/docker-without-containers-pulldocker/ .

Note. I work for Terminal.com. We use a non-LXC, non-libcontainer implementation of container technology (for example, which has no AUFS restrictions). We are trying to make containers that work like full Linux machines, and I think we are there. Give it a try.
