From Docker basics to cluster management
3 minute intro?
Format Interfaces Cache Registry
Where’s on ?
Dockerized Agents
Docker Task!(since 5.8)
• Dynamic port mapping• Mount multiple volumes• Set the working directory• Add additional arguments
New in Bamboo 5.9

Orchestration is the next arena
What’s Orchestration?
Docker’s Own Orchestration
machine swarmcompose
• Provision a machine on a PaaS• Pull PostgreSQL and• Stash from the Registry• Use Compose to start the app• Tear down the machine
The plan for the first DEMO
$ docker-machine create -d virtualbox dev
INFO[0000] Downloading boot2docker.iso from... INFO[0001] Creating SSH key... INFO[0001] Creating VirtualBox VM... INFO[0006] Starting VirtualBox VM... INFO[0007] Waiting for VM to start... INFO[0041] "dev" has been created and is now active
• “docker-machine create” to provision the host• Edit “docker-compose.yml” to describe our app• “docker-compose up -d” to start our application• “docker-machine rm atlascamp-standalone" to
remove it
Recap of what you saw

scheduler
• Strategies• Spread• Binpack• Random
• Filters• Constraint• Affinity• Port• Dependency• Health
Swarm comes with strategies and filters
$ docker run -e \ constraint:instance==database --name db
• Provision a Docker swarm• Made up of three hosts
• master node• node with 2gb of RAM• simple node
• Use labels to deploy to nodes• Run Stash and PostgreSQL on
different nodes
The plan for the second DEMO
$ docker pull swarm
$ docker run --rm swarm create 6856663cdefdec325839a4b7e1de38e8
