Installing Docker onto a Synology NAS is the normal click click click sort of workflow.
Synology HDD compatibility How to Install XPEnology Tinycore Redpill
The first thing to do is to enable SSH login on Diskstation. To do this, go to the “Control Panel” > “Terminal”
After that you can log in via “SSH”, the specified port and the administrator password (Windows users take Putty or XShell or mRemoteNG).
I log in via Terminal, winSCP or Putty and leave this console open for later. Optionally you can login directly with Windows OpenSSH client: https://docs.microsoft.com/en-us/windows-server/administration/openssh/openssh_install_firstuse?tabs=gui
The authenticity of host '[synology.local](0.0.0.0)' can't be established.
ECDSA key fingerprint is SHA256:1234567890abcdef1234567890abcdef1234567890a.
Are you sure you want to continue connecting (yes/no)? yes

I create a new directory called “jenkins” in the Docker directory, as well a a “docker-compose.yml” file.
mkdir -p /volume1/docker/jenkins/
cd /volume1/docker/jenkins
touch docker-compose.yml
mkdir -p data
Docker Compose file contains:
version: '2.0'
services:
jenkins:
restart: always
image: jenkins/jenkins:lts
privileged: true
user: root
ports:
- 8081:8080
container_name: jenkins
volumes:
- ./data:/var/jenkins_home
- /var/run/docker.sock:/var/run/docker.sock
- /usr/local/bin/docker:/usr/local/bin/docker
I can also make good use of the console in this step. I start the Jenkins server via Docker Compose.
sudo docker-compose up -d
After that I can call my Jenkins server with the IP of the diskstation and the assigned port from “Step 2”.
Enter the password that we captured from the file at /var/jenkins_home/secrets/initialAdminPassword after installing Jenkins.
I recommend just installing the recommended plugins first up. You can always add or remove plugins later.
Some plugins to install:
- ✓ Git parameter
- ✓ AnsiColor
- ✓ Build with Parameters
- ✓ Github
- ✓ Kubernetes Credentials
- ✓ Environment Script
- ✓ CloudBees Docker Build and Publish
Some plugins to remove (if not needed):
- ✕ SSH Build Agents
- ✕ SSH server + (Mina SSHD API :: Core, Mina SSHD API :: Common)
Enter the container
docker exec -it jenkins /bin/bash
Get the random admin password generated
cat /var/jenkins_home/secrets/initialAdminPassword
