- Introduction Scale Out with Docker Swarm
- Docker-machine
- Private registry
- Initial source
- Update source
- Update s3
- Build image
- Build image and change tag with localhost:5000
- Build image with localhost:5000 for private repository
- Push Image to Pirvate registry
- Run stack
- Stop stack
- Changing Scale
- Update latest image
- Trouble shooting
- Docker Swarm with Jenkins
CW-OVP can have many background job for video packaging and encoding with ffmpeg.
You must do scale out in production environment due to you require HA and saving time.
If you want get scale in, you can get it but you know scale in cost is expensive more than scale out.
I provide scale out of solution with docker swarm.
I recommend 16 core for each server of worker node but mininum spec is 4 or 8 or more core.

If you want run on local PC or docker-machine driver with aws or digital ocean or another cloud service that support docker-machine, Do use docker-machine. But if you don't wanna docker-machine, bypass this section go to next section of Private registry
- Reference
brew install virtualbox
brew install docker-machine
docker-machine create -d virtualbox master
docker-machine create -d virtualbox worker1
docker-machine create -d virtualbox worker2
docker-machine ls
aws
docker-machine create -d amazonec2 \
--amazonec2-region us-west-1 \
--amazonec2-instance-type "m5.large" \ #--amazonec2-instance-type "t2.micro" \
--amazonec2-ssh-keypath ~/.ssh/id_rsa \ #--amazonec2-ssh-keypath ~/.ssh/ssh_key \
aws-test
if you don't have virtualbox. you got blow of message.
VBoxManage not found. Make sure VirtualBox is installed and VBoxManage is in the path.
docker-machine ssh master

docker@master:~$ docker swarm init --advertise-addr 192.168.99.100
Swarm initialized: current node (4l396ni602807sb2hk1ujlvm5) is now a manager.
To add a worker to this swarm, run the following command:
docker swarm join --token SWMTKN-1-5jcphjyj4ykejxphj2o15yh7bz4syyxo5qg8bt25ldkhd4poez-1l2skxj2931mtjolwd43139jy 192.168.99.100:2377
To add a manager to this swarm, run 'docker swarm join-token manager' and follow the instructions.
if you want get token for worker again
docker swarm join-token worker
docker-machine ssh worker1
