Setting up Codespaces IDE for puppet
After installing Docker-Engine and Docker-Compose, change directory into the corresponding tool you want to setup the environment for.
Then all you need to do is to run
docker-compose up -d
This single command will initialize your Codespaces IDE.
Use Codespaces IDE
To use Codespaces IDE,
- Open your browser.
Visit your machine's IP with port 8000. (Ex. http://192.168.0.60:8000 or http://localhost:8000)
Now you will be presented with the Codespaces IDE console.
|Containers||Purpose||OS||Port Exposed||Host Port Mapped|
|node1||Load Balancer||Centos 6.8||80||81|
|node2||App Server||Centos 6.8||80||82|
|node3||App Server||Centos 6.8||80||83|
Once created, you may want to stop the codespaces environment, or at times might have to recreate it completely, or reset a certain node. This section describes how to do so.
Stopping codespaces environment
If you would like to stop the environment created earlier, its as simple as the follows,
run the following from your codespaces directory
cd cs-puppet docker-compose stop
The above command will shut down the containers/bring those to stopped state. You could easily start it all again, by running the following command from the same directory.
cd cs-puppet docker-compose up -d
Resetting the nodes/environment
Since this is a docker based environment, its easy to rest a node, or even the complete environment.
To reset a node,
- Find out the name of the node from docker-compose.yml
services: puppet: image: codespaces/puppet-master:2.0.0 ports: - "8000:8000" - "80:80" environment: JAVA_ARGS: "-Xms256m -Xmx256m -XX:MaxPermSize=256m" volumes: - workspace:/workspace networks: - puppet container_name: puppet domainname: codespaces.io hostname: puppet restart: always node1: image: codespaces/puppet-node-centos-6:v0.1.3 ports: - "81:80" networks: - puppet container_name: node1 domainname: codespaces.io hostname: node1 restart: always
In the above snippet of node, there are two nodes viz puppet and node1
You could alternately use the following command to find the node name
- Once you decide which node you are resetting, run the following command to redo it. I am taking an example of a node by name node1
docker-compose stop node1 docker-compose rm node1 docker-compose up -d node1
Replace the name of actual node with lb. That should help you redo the node
To reset the complete environment,
docker-compose down docker-compose up -d
The above command will recreate the nodes, without deleting your workspaces. Any files that you had created would still be available after you re launch the environment.
