Google Compute Engine

1. Create a compute instance
1.Click create VM instance in google cloud console.
2.Select a preferred Machine Type (Default : 1cpu, 3.75GB Memory).
3.Select a Linux image (Default Debian/ ubuntu).
4.Allow HTTP/S Traffic.
2. SSH to the instance
Connect to the instance by SSH or connect via browser on port other than 80.
3. run the following to install docker
sudo wget -qO- https://get.docker.com/ | sh
4. Create a container network
docker network create chatNetwork
5. install a docker image for mongo db
1
sudo docker run --name mongo --network chatNetwork -d mongo \
2
--smallfiles --oplogSize 128 --replSet rs0 --storageEngine=mmapv1
Copied!
6. Configure a mongo db replica set
ssh in to the mongodb docker container sudo docker exec -it mongo mongo
Execute this following script to create a replica set rs.initiate({ _id: 'rs0', members: [ { _id: 0, host: 'localhost:27017' } ]})
Exit docker container
7. install a docker image for rocketchat
ROOT_URL should be substituted for your own domain:
1
docker run --name rocketchat -d -p 80:3000 \
2
--network chatNetwork --env PORT=3000 \
3
--env ROOT_URL=https://www.test.com \
4
--env MONGO_URL=mongodb://mongo:27017/rocketchat \
5
--env MONGO_OPLOG_URL=mongodb://mongo:27017/local rocket.chat:latest
Copied!
You are now running rocket chat on compute engine. You can open a browser with the external IP of the instance.
If you want the containers to start each time the instance reboots configure the following to the instance.
Click on the instance in the and hit "edit"
Under "Custom metadata" add an item with
