Berikut langkah untuk install docker menggunakan ansible sebagai tools otomasi dengan debian 11.07.
- Server Debian OS for remote host
- Server Debian OS for docker1 node
- install ansible di debian 11.07 (remote host) dan jalankan perintah di bawah ini
sudo apt update
sudo apt install ansible - generate private dan public key kemudian copikan ssh key ke dalam host server
sudo ssh-keygen
ssh-copy-id [email protected] - Buat file host inventory dengan menjalankan perintah di bawah ini :
sudo nano /etc/ansible/hosts - Tambahkan baris konfigurasi pada file hosts di bawah ini :
[servers]
docker1 ansible_host=172.17.100.18simpan file tersebut
- Jalankan perintah untuk melakukan inventory list
ansible-inventory –list -y - Lakukan ansible test connect to hosts, dengan perintah di bawah ini
ansible all -m ping -u root - Jalankan docker di target dengan ansible playbook yml, buat file docker-ansible.yml yang berisi di bawah ini :
- name: install ke docker1
hosts: docker1
remote_user: docker1
become: yes
tasks:
- name: Install Docker Engine
apt:
name: docker.io
state: present
- name: Install Docker CLI
apt:
name: docker-compose
state: present
- name: Start Docker service
service:
name: docker
state: started
enabled: true
- name: Pull nginx Docker image
docker_image:
name: nginx
source: pull
- name: Create volume
docker_volume:
name: nginx-data
driver: local
- name: Run nginx Docker container
docker_container:
name: nginx
image: nginx
state: started
ports:
- "80:80"
volumes:
-“nginx-data:/usr/share/nginx/html:ro”
10. Jalankan playbook dengan perintah
ansible-playbook docker-ansible.yml11. jika error seperti di bawah ini tambahkan konfigurasi sudoers pada direktori /etc/sudoers.d/docker1
remote@remote:~$ ansible-playbook docker-ansible.yml
PLAY [install ke docker1] ***********************************************************************************************
TASK [Gathering Facts] **************************************************************************************************
fatal: [docker1]: FAILED! => {“msg”: “Missing sudo password”}
PLAY RECAP **************************************************************************************************************
docker1 : ok=0 changed=0 unreachable=0 failed=1 skipped=0 rescued=0 ignored=0
sudo nano /etc/sudoers.d/docker1
docker1 ALL=(ALL) NOPASSWD: ALL
12. Kemudian jalankan kembali perintah ansible playbook
ansible-playbook docker-ansible.yml
remote@remote:~$ ansible-playbook docker-ansible.yml
PLAY [install ke docker1] ***********************************************************************************************
TASK [Gathering Facts] **************************************************************************************************
ok: [docker1]
TASK [Install Docker Engine] ********************************************************************************************
changed: [docker1]
TASK [Install Docker CLI] ***********************************************************************************************
changed: [docker1]
TASK [Start Docker service] *********************************************************************************************
ok: [docker1]
TASK [Pull nginx Docker image] ******************************************************************************************
changed: [docker1]
TASK [Create volume] ****************************************************************************************************
changed: [docker1]
TASK [Run nginx Docker container] ***************************************************************************************

PLAY RECAP **************************************************************************************************************
docker1 : ok=7 changed=5 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0
13. kita lakukan check docker yang sudah terinstalasi di host/target docker1
systemctl status docker.service
docker1@docker1:/$ systemctl status docker.service
● docker.service – Docker Application Container Engine
Loaded: loaded (/lib/systemd/system/docker.service; enabled; vendor preset: enabled)

└─5858 /usr/sbin/docker-proxy -proto tcp -host-ip 0.0.0.0 -host-port 80 -container-ip 172.18.0.2 -conta
14. lakukan cek container apakah sudah up atau belum di host docker1
sudo docker container ls -a
docker1@docker1:/$ sudo docker container ls -la
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
edc5fcb52b99 nginx “/docker-entrypoint.…” 3 minutes ago Up 3 minutes 0.0.0.0:80->80/tcp nginx
15. lakukan tes halaman website dengan alamat IP docker1 dari komputer remote
curl http://172.17.100.18
remote@remote:~$ curl http://172.17.100.18
