Setup Docker Swarm Dan Portainer pada 3 Node

Apa yang diperlukan adalah minimum dua atau tiga server untuk cluster server.

Sediakan tiga server .

1 server untuk Manager (Boleh ada banyak manager tapi hanya ada 1 leader dalam 1 masa)
2 server lagi untuk Worker

node1 192.168.1.45 (Manager)
node2 192.168.1.44 (Worker)
node3 192.168.1.48 (Worker)

Setiap server perlu install Docker dan Docker Compose

Node1

Docker Installation

 sudo apt-get update

 sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

 echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io

sudo docker version

Refer Here for detail

https://docs.docker.com/engine/install/ubuntu/

Kemudian Install Docker Compose

Docker Compose: https://docs.docker.com/compose/install/

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

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

$ docker-compose --version

Ulang step ini untuk Node2 dan Node3

Docker Installation

 sudo apt-get update

 sudo apt-get install \
    apt-transport-https \
    ca-certificates \
    curl \
    gnupg \
    lsb-release

 curl -fsSL https://download.docker.com/linux/ubuntu/gpg | sudo gpg --dearmor -o /usr/share/keyrings/docker-archive-keyring.gpg

 echo \
  "deb [arch=amd64 signed-by=/usr/share/keyrings/docker-archive-keyring.gpg] https://download.docker.com/linux/ubuntu \
  $(lsb_release -cs) stable" | sudo tee /etc/apt/sources.list.d/docker.list > /dev/null

sudo apt-get update

sudo apt-get install docker-ce docker-ce-cli containerd.io

sudo docker version

Refer Here for detail

https://docs.docker.com/engine/install/ubuntu/

Kemudian Install Docker Compose

Docker Compose: https://docs.docker.com/compose/install/

sudo curl -L "https://github.com/docker/compose/releases/download/1.29.2/docker-compose-$(uname -s)-$(uname -m)" -o /usr/local/bin/docker-compose

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

$ docker-compose --version

Setelah semua node install docker dan docker compose teruskan langkah seterusnya

enable docker swarm Manager di Node1

docker swarm init

If above command is failing use the below:

docker swarm init --advertise-addr "ipaddress"

Enable Docker Swarm Worker di node2 dan node3

docker swarm join --token SWMTKN-1-1xxxxxxxxxxxxxza8ryxxxxx9gbbs 192.168.X.45:2377

Nak dapatkan balik token :

docker swarm join-token manager or docker swarm join-token worker

Lepas tu install portainer dekat Node1

curl -L https://downloads.portainer.io/portainer-agent-stack.yml -o portainer-agent-stack.yml

docker stack deploy -c portainer-agent-stack.yml portainer

Selesai
