- Enable docker to use the insecure registry by creating the
/etc/docker/daemon.jsonfile:
$ sudo vi /etc/docker/daemon.json
with this content:
{
"insecure-registries": [
"localhost:5000"
]
}- Restart docker:
$ sudo systemctl restart docker
- Download some required programs:
$ sudo curl -L -o /usr/local/bin/jq https://github.com/stedolan/jq/releases/download/jq-1.6/jq-linux64
$ sudo curl -L -o /usr/local/bin/docker-compose https://github.com/docker/compose/releases/download/1.23.1/docker-compose-Linux-x86_64
$ sudo curl -L -k -o /usr/local/bin/cfssl https://pkg.cfssl.org/R1.2/cfssl_linux-amd64
$ sudo curl -L -k -o /usr/local/bin/cfssljson https://pkg.cfssl.org/R1.2/cfssljson_linux-amd64
$ sudo chmod +x /usr/local/bin/{jq,docker-compose,cfssl,cfssljson}
- Create some directories:
$ mkdir -p registry/{certs,storage}
- Create self-signed certs:
$ ./tls-gen.sh
$ cp -p ca/certs/registry-server.* registry/certs
- Start the docker registry
$ docker-compose up -d
- Test it out
$ docker pull alpine:3.8
$ docker tag alpine:3.8 localhost:5000/alpine:3.8
$ docker push localhost:5000/alpine:3.8
The push refers to repository [localhost:5000/alpine]
