Set up local Registry for DockerSwarm

docker run -d -p 5000:5000 --restart=always --name registry registry:2

To access this local registry you need to allow insecure registrys in your daemon config for your docker.

Ubuntu / Debian

Edit or create /etc/docker/daemon.json and add

{ "insecure-registries":["myregistry.example.com:5000"] }

with the URL of your customer regitry.

Docker Cluster

Create the swarm

docker swarm init --advertise-addr <MANAGER_IP>

Push images to local regitry

To allow docker swarm to be deployed from a docker-compose.yml file we need to have our locally built images pushed to some registry to be referenced from. This is where we use our local registry.

Tag and push all images required

docker-compose build # Tags builds images for push
docker-compose push

Or you can push individually

docker tag redischat_web:latest <ip>:5000/redis_web
docker push <ip>:5000/redis_web

Copy the token string and use to attach other nodes to this server

TODO

Running this app in cluster seems to not sticky session sockets

Architecture

All Dockerfiles have their respective armv7 architecture next to base image
