1. Setup Docker

1.1 Download Docker binaries
cd /usr/local/bin
sudo wget https://master.dockerproject.org/linux/ppc64le/dockerd https://master.dockerproject.org/linux/ppc64le/docker-proxy https://master.dockerproject.org/linux/ppc64le/docker-runc https://master.dockerproject.org/linux/ppc64le/docker https://master.dockerproject.org/linux/ppc64le/docker-containerd https://master.dockerproject.org/linux/ppc64le/docker-containerd-shim https://master.dockerproject.org/linux/ppc64le/docker-containerd-ctr
sudo chmod +x * 

1.2 create file /etc/init/docker.conf with:

description "Docker daemon"

stop on runlevel [!2345]
limit nofile 524288 1048576
limit nproc 524288 1048576

respawn

kill timeout 20

end script

1.3 
sudo ln -s /etc/init/docker.conf /etc/init.d/docker

1.4 Add local Docker registry to DOCKER_OPTS
sudo bash -c 'cat >> /etc/default/docker' << EOF
DOCKER_OPTS="--insecure-registry IP_ADDRESS:5000"
EOF

1.5 Start docker 
sudo service docker start

2. Docker registry
2.1 Download docker registry project
git clone --recursive https://github.com/barthy1/distribution
sudo docker build -t ppc64le_registry .

3. Native basic auth as per https://docs.docker.com/registry/deploying/#/native-basic-auth
3.1 
mkdir auth
sudo docker run --entrypoint htpasswd ppc64le_registry -Bbn $USER $PATH  > auth/htpasswd
sudo docker login -u concourse_user -p conc_pass 140.211.168.97:5000

3.2 TLS configure as per https://docs.docker.com/registry/insecure/#/using-self-signed-certificates
use ip address as CN

mkdir certs
mkdir -p certs && openssl req \
-newkey rsa:4096 -nodes -sha256 -keyout certs/domain.key \
-x509 -days 365 -out certs/domain.crt

4. Run container with Docker registry
docker run -d -p 5000:5000 --restart=always --name registry \
  -v `pwd`/auth:/auth \
  -e "REGISTRY_AUTH=htpasswd" \
  -e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
  -e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
  -v `pwd`/certs:/certs \
  -e REGISTRY_HTTP_TLS_CERTIFICATE=/certs/domain.crt \
  -e REGISTRY_HTTP_TLS_KEY=/certs/domain.key \
  ppc64le_registry:latest
