Deploy Microservices using Docker-swarm and HAProxy

Step 1 :

NOTE: Make sure that you have installed docker in each nodes

ssh into Node

kivsithvothy@Kivs-MBP ~ % ssh root@your-public-ip

Step 2 :

• Create a new docker-swarm

root@swarm-node~# docker swarm init

Swarm initialized: current node (b4etd4utcgn9xnpawfs2tf5qe) is now a manager.

To add a worker to this swarm, run the following command:

    docker swarm join --token SWMTKN-1-0hbyhpos06fwf85r35319wyhjpfysk9l88emio2av1qsr04alu-8th0xvea2f0yw3voiqc5er32c 192.168.99.100:2377

To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.

• Go to the other worker nodes and join the worker nodes to swaram manager

root@swarm-node~# docker swarm join --token SWMTKN-1-0hbyhpos06fwf85r35319wyhjpfysk9l88emio2av1qsr04alu-8th0xvea2f0yw3voiqc5er32c 192.168.99.100:2377

root@swarm-node~# docker ndoe ls

Step 3 :

Run a command

• Clone the repository

root@swarm-node~# git clone https://github.com/UP-DevOps-Class-Org/DevOps-microservices-app.git

root@swarm-node~# cd DevOps-microservices-app

• Deploy all microservices

root@swarm-node~# python3 deploy.py all

• Deploy one microservice

root@swarm-node~# python3 deploy.py app1_name

• Deploy multi microservices

root@swarm-node~# python3 deploy.py app1_name app2_name app3_name

Run docker container

docker run -d -p 7500:7500 image-id
