dkr

Docker for Docker containers?

This project was inspired by Liz Rice

deps

1. go (golang)
2. ./scripts/fs.sh (this pulls minirootfs)

build

./scripts/build.sh

boot container host

docker-compose up --build

run dkr in container host

docker-compose exec --privileged dkr ./dkr run /bin/sh

Here you will be in a shell.

Example of hostname manipulation of dkr container instead of the docker container:

dkr $ docker-compose exec --privileged dkr ./dkr run /bin/sh
2020/05/27 23:49:24 run() executing [/bin/sh]
2020/05/27 23:49:24 fork() executing [/bin/sh]
/ # hostname
f60818cfd391
/ # hostname dkr
/ # hostname
dkr
/ # exit
dkr $ docker-compose exec --privileged dkr ./dkr run /bin/sh
2020/05/27 23:51:17 run() executing [/bin/sh]
2020/05/27 23:51:17 fork() executing [/bin/sh]
/ # hostname
f60818cfd391
/ #

See how the running docker-compose up --build continainer still has the same hostname?

Yea we did it!!

linux

If you are already on linux just:

# pulls minitrootfs
./scripts/fs.sh
# builds dkrd and dkr linux bins
./scripts/build.sh

sudo MINIROOTFS_HOME=$(pwd) ./dkr /bin/bash
