Describes how to build docker image warehouse on your own server

I. check the docker version of the host computer

If the version is less than 17, you need to download a new version of docker. If your version of docker is more than 17, skip below and jump directly to the second block.

docker -v

1. Update yum source

yum update

2. Unload the old version of docker, if installed

sudo yum remove docker  docker-common docker-selinux docker-engine

3. Software packages needed for installation

sudo yum install -y yum-utils device-mapper-persistent-data lvm2

4. Setting up yum source

sudo yum-config-manager --add-repo https://download.docker.com/linux/centos/docker-ce.repo

5. View all docker versions in the warehouse and select the download

yum list docker-ce --showduplicates | sort -r

6. Install docker

sudo yum install docker-ce-<Version number>

7. Start up and add boot-up self-start

sudo systemctl start docker
sudo systemctl enable docker

8. Install the latest docker-compose

# download
wget https://github.com/docker/compose/releases/download/1.24.1/docker-compose-Linux-x86_64
# Move to / user/local/bin
mv docker-compose-Linux-x86_64 /user/local/bin
# Rename
mv docker-compose-Linux-x86_64 docker-compose

9. Use executable permissions for binary files

sudo chmod +x /usr/local/bin/docker-compose

2. Warehouse Construction

1. Download Harbor

Github address: https://github.com/vmware/harbor/releases/, you can download the version of your choice

# download
wget https://storage.googleapis.com/harbor-releases/release-1.9.0/harbor-online-installer-v1.9.0.tgz
# decompression
tar xvf harbor-online-installer-v1.9.0.tgz

2. Configuring Harbor

Go to the Harbor folder, find the harbor.yml file, and configure it

vim /harbor/harbor.yml

Generally configure these two items, other self-determined configurations, hostname for your harbor server IP or server domain name, port for the exposed port (I configure 5000 here), must not be localhost or 127.0.0.1, save and exit after modification.

3. Start up

Start harbor in the harbor folder by executing the following command

./install.sh

After startup, the browser accesses http://the IP or domain name you set: the port you set, the account defaults to admin, password: Harbor12345, after login, it enters the home page.

4. New projects

Here we have a project called guojing.

5. push Mirror

Modified configuration

Since the docker version starts at 13, register s can only use https. Since all of our files are http, we need to create a daemon.json file in the / etc/docker / directory and add the following

{ "insecure-registries":["xxx:5000"] }

Restart docker

systemctl restart docker

Restart harbor-related containers, because they are closed after restarting docker, so we find all harbor-related images through docker ps-a, and restart the container name through docker restart xx xx xx

Official submission of mirrors

For example, submit a local maven image, and xxx configures the hostname when you configure harbor

# Login first
docker login xxx:5000
# Label
docker tag maven xxx:5000/guojing/maven:latest
# Submission
docker push xxx:5000/guojing/maven:latest
