How to build CloudStack using Docker

Introduction

I built CloudStack to understand CloudStack, but I stumbled a bit at that time, so I decided to write this article. There are various ways to build CloudStack, but this time we will use Docker.

Development environment

MacBook Pro (Mojave 10.14.6) Docker (19.03.13) docker-compose (1.27.4)

What is CloudStack Simulator?

The CloudStack simulator is a Docker image officially provided by CloudStack. The simulator is running in one container except for the management DB. (Since I am not familiar with CloudStack, I would appreciate it if you could point out any mistakes.)

Since the image of the simulator is registered in Docker Hub, we will use it this time. https://hub.docker.com/r/cloudstack/simulator

I actually moved it

docker pull cloudstack/simulator
docker run --name cloudstack -d -p 8080:8080 cloudstack/simulator

I tried to run it as officially and tried to access http: // localhost: 8080 / client, but an error occurred as shown in the image below. I didn't know what was happening just by looking at this, so I decided to check what kind of error was occurring.

docker run --name cloudstack -p 8080:8080 cloudstack/simulator

ERROR [c.c.u.d.Merovingian2](main:null) (logid:) Unable to get a new db connection
com.mysql.jdbc.exceptions.jdbc4.MySQLNonTransientConnectionException: Could not create connection to database server. Attempted reconnect 3 times. Giving up.

At first glance, it seems that you can't connect to MySQL? So, when I looked it up, I found issue regarding the above error.

However, since the issue was closed, I thought that the image of Docker Hub was old, so I decided to build it from the Latest release.

The main subject from here

So, I will use Latest release of official repository. Files related to Docker are under tools / docker.

** Please clone as it is because you need files other than Docker related files at build time. ** **

Run Docker-compose. Probably, by executing this command, the management DB of CloudStack is started.

docker-compose -f tools/docker/docker-compose.yml up -d

Next, build the image from the Dockerfile, but if it is the cloned Dcokerfile, a pip error will occur, so fix it.

CMD ["/usr/bin/supervisord"]

To make the image easier to understand, specify the same tag name as the CloudStack version and build it. If you can launch the container using the built image and access http: // localhost: 8080 / client, it is successful. It takes a long time to start up, so you may want to remove the -d option if you want to check if it is working properly.

docker build -t cloudstack/simulator:4.13.1.0 . -f tools/docker/Dockerfile 
docker run --name cloudstack -d -p 8080:8080 cloudstack/simulator:4.13.1.0

This is the screen when you can access it.

Finally

I introduced it briefly in the article, but due to the lack of references, I made a lot of trial and error. I hope this article helps someone who is as stumbling as I am.
