Sample Django app on Docker Swarm

A sample Django app to test Docker Swarm features.

Requirements

• Docker
• A Docker Cloud account (https://cloud.docker.com)

Installation in dev

git clone https://github.com/sophilabs/sample-django-docker-swarm.git
docker-compose build

Run the app in your local environment

docker-compose up -d

Navigate to http://localhost

Installation on a Swarm

1. Upload images

First thing to do is to upload the built images to Docker cloud.

docker login
docker-compose build
./upload-images.sh <account name>

2. Create Swarm via Docker Cloud

Then, you need to create your Docker Swarm by following the steps on Docker Cloud.

3. Connect to the Swarm

Once created, copy the command available to run the docker cloud client in your environment.

It will require changing the DOCKER_HOST environment variable.

export DOCKER_HOST=tcp://127.0.0.1:<port>

Check you are connected to the swarm by listing the Swarm nodes.

docker node ls

4. Upload the stack

docker login
./deploy-stack.sh

5. Play and learn

You can modify many aspects of your running services. Run :bash:`docker service update --help` to see a list of options.

Update service image

docker service update --image <account>/<image>:<tag> <service>

Update service replicas

docker service update --replicas <number> <service>
