Docker Harbor private server construction and use

Article source: Tao Teacher operation notes – wechat official account

1. Introduction

Although Docker officially provides a public mirror warehouse, it is necessary to deploy Registry in our private environment from the perspective of security and efficiency. This article introduces Harbor private server construction and use.

Harbor is an open source enterprise Docker Registry project managed by VMware, including rights management (RBAC), LDAP, log audit, management interface, self-registration, image replication and Chinese support, etc. Official address: github.com/goharbor/ha…

2. Prepare the environment

Docker and Docker-compose are required for Harbor installation.

2.1 Software Environment

software	version	note
The operating system	centos7	–
docker	Docker version 18.06.1 – ce	–
docker-compose	Docker – compose version 1.24.1	–

2.2 Hardware Environment

 $docker --version
Copy the code

3.2 installation DockerCompose

# install the epel - release
 yum install epel-release
# python installed - PIP
 yum install -y python-pip
# installation docker - compose
 pip install docker-compose
# install git
 yum install git
Docker-compose version number
 docker-compose -version
Copy the code

4. The Harbor installation

Main steps: 1. Download the Installer. 2. Configuration harbor. Yml; 3. Run install.sh and start Harbor.

4.1 Downloading Software:

Download software: github.com/goharbor/ha…

wget 'https://storage.googleapis.com/harbor-releases/release-1.8.0/harbor-offline-installer-v1.8.4-rc1.tgz' .

# decompressionThe tar - ZXVF harbor - offline installer - v1.8.4 - rc1. TGZCopy the code

4.2 Modifying the Configuration

If you download the file and unzip it, you will find the harbor configuration file.

Installation and configuration instructions: github.com/goharbor/ha…
To configure HTTPS: github.com/goharbor/ha…

Modify hostname,harbor_admin_password, and the result is as follows.

#harbor.yml
cat harbor.yml |grep -v The '#' |grep -v '^ $'
hostname: registry.test.myop.com
http:
  port: 80
harbor_admin_password: Harbor12345
database:
  password: root123
data_volume: /data1/harbor
clair: 
  updaters_interval: 12
  http_proxy:
  https_proxy:
  no_proxy: 127.0. 01.,localhost,core,registry
jobservice:
  max_job_workers: 10
chart:
  absolute_url: disabled
log:
  level: info
  rotate_count: 50
  rotate_size: 200M
  location: /var/log/harbor
_version: 1.8. 0

Docker-composing. Yml: docker-composing. Yml: docker-composing. Yml: docker-composing.
vim docker-compose.yml,
   dns_search: 
   ports:
      - 5000: 5000
Copy the code

The hostname set native registry.test.myop.com here, harbor_admin_password web page code.

4.4 Test Access

The default account is admin, and the default password is Harbor12345 (which is what you set in your office profile, if not changed).

5. Harbor operations

5.1 stop Harbor

If you want to stop it, or if the server is restarted, you need to restart it manually by executing a command in the Harbor installation directory.

#Removing Harbor's containers while keeping the image data and Harbor's database files on the file system
$ sudo docker-compose down -v
$ vim harbor.yml
$ sudo prepare
$ sudo docker-compose up -d
Copy the code

5.2 Reinstallation

You may want to remove Harbor’s database and Image data from a complete reinstall. (Risky!)

$ rm -r /data/database
$ rm -r /data/registry
Copy the code

Modify installation configuration: Installation description: github.com/goharbor/ha…

5.3 Changing a Port

Vim docker-comemage. yml, change port 80 to 8888.

#vim docker-compose.ymlProxy: image: goharbor/nginx -Photon :v1.7.5 container_name: nginx restart: always cap_drop: -all cap_add: - CHOWN - SETGID - SETUID - NET_BIND_SERVICE volumes: - ./common/config/nginx:/etc/nginx:z networks: - harbor dns_search: . ports: - 8888:80 - 443:443 depends_on: - postgresql - registry - core - portal -log

Copy the code

5.4 Troubleshooting

Docker-compose ps, then you can log into the Docker container to check the problem.

cd /data1/harbor Harbor installation directory
$docker-compose stop
$docker-compose start
$docker-compose ps Name Command State Ports --------------------------------------------------------------------------------------------- harbor-core /harbor/start.sh Up (healthy) harbor-db /entrypoint.sh postgres Up (healthy) 5432/tcp harbor-jobservice /harbor/start.sh  Up harbor-log /bin/sh -c /usr/local/bin/ ...

Up 6379/tcp registry /entrypoint.sh /etc/regist ... Up (healthy) 5000/tcp registryctl /harbor/start.sh Up (healthy)Copy the code

5.5 the Https configuration

Harbor Https configuration: CentOS7 Harbor Https configuration github.com/goharbor/ha…

Harbor has been built. There may be some problems when we upload the project. There will be errors when we log in Harbor on another server (client).

$docker login  registry.test.myop.com
Error response from daemon: Get https://registry.test.myop.com/v2/: dial tcp registry.test.myop.com:443: connect: connection refused
Copy the code

This is because the default docker Registry uses HTTPS from docker1.3.2. We set Harbor to use HTTP by default. Therefore, when executing docker login, pull, push and other commands to operate non-HTTPS Docker regsitry, an error will be reported.

Solutions:

Edit docker configuration files for Harbor and client machines

If the system is Centos7, you can change it in /etc/docker-daemon. json.
If the system is MacOS, you can click “Preference” in “Advanced” to add harbor_ip in “Insecure Registry” and restart the Docker client.

vim /etc/docker/daemon.json
{
 "insecure-registries": [
 "harbor_ip or harbor_domain"]}Copy the code

On the Harbor server, in the Harbor installation directory

Docker-comemage. yml: docker-comemage. yml: docker-comemage. yml: docker-comemage. yml
vim docker-compose.yml
    dns_search: 
    ports:
      - 5000:5000
Copy the code

3. Restart or reinstall harbor

$docker-compose stop
$docker ps -a |grep harbor |awk '{print $1}'|xargs -I {}  docker rm  {} 
Removing Harbor's database and image data
$ rm -r /data1/database
$ rm -r /data1/registry
Docker-compose start
docker-compose start

#reload docker 
systemctl daemon-reload
#docker ps |grep -v CONTAINER |awk '{print $1}'>docker_online.txt
#cat docker_online.txt |while read line; do echo "$line"; docker start $line; done;
#systemctl start Docker # service will stop. Use reload.
systemctl reload docker
systemctl status docker.service -l
Copy the code

4. Log in to the warehouse

Harbor machine test login

 docker login registry.test.myop.com
Username: admin
Password: 
WARNING! Your password will be stored unencrypted in /root/.docker/config.json.
Configure a credential helper to remove this warning. See
https://docs.docker.com/engine/reference/commandline/login/#credentials-store

Login Succeeded
Copy the code

If you log in to a remote machine, the same error occurs.

vim /etc/docker/daemon.json
{
 "insecure-registries": [
 "harbor_ip or harbor_domain"]}$systemctl daemon-reload
$docker ps 
$systemctl reload docker 
$systemctl  status docker.service -l
Copy the code

Note: Some articles say HTTPS login error, need to modify docker.service as follows. Docker. Service does not need to be modified under Docker Version 18.06.1 or Harbor-1.8.4.

 #vim /lib/systemd/system/docker.service
Add the following configuration. This is not required in this environment docker 18.06.1
#ExecStart=/usr/bin/dockerd --insecure-registry=harbor_ip
Copy the code

6. Use Harbor

6.1 web interface

Go to https://harbor_ip to set up projects, users, etc.

6.2 mirror pull/push

Json {“insecure-registries”:[“registry.test.myop.com”]} systemctl restart docker 2, tagging docker tag centos: 6 registry.test.myop.com/library/centos:6 3, upload docker push Registry.test.myop.com/library/centos:6 4, download the docker pull registry.test.myop.com/library/centos:6

Example:

# Login to Harbor before pushingDocker login Docker login registry.test.myop.com admin Harbor12345 Docker images to upload the image to Harbor, run the following command# Mirror tagDocker tag Image name: private server address/repository project name/image name: tag# Push to private serverDocker push private server address/warehouse project name/image name: tag# pull image from private serverDocker Pull private server address/repository project name/image name: tagCopy the code
