@ehazlett

2. Dockerizing Applications
● Building an Image
● Swarm Cluster
● Building a Stack
● Operations
○ Deployment
○ Monitoring
○ Scaling
○ Logs

3. Image
● Built from Dockerfile
● Application dependencies are bundled
● Can be “shipped” around and shared
● Enables portability

4. Swarm
● Group of machines running Docker in Swarm mode (cluster)
● Easy deployment (docker swarm init; docker swarm join)
● Enables multi-container, multi-node applications
● Production Features
○ Deployment Policies
○ Application Scale
○ Configs
○ Secrets
○ Etc.
● Simple Deployment of Stacks

5. Stack
● Group of related services
● Uses Docker Compose syntax (with some exceptions)
● Simple to create and understand
● Enables consistent deployments for local dev and
production
