Containers (Docker)

Advantages

• Quick to start/restart

• Portability

• Isolation

• Resource allocation and scheduling

Challenges

• Data persistence

• Additional networking complexity

• Microservice Overhead


Container Persistent Data challenges

• Container file systems are based on UnionFS and not appropriate for high IO throughput

• Volumes let you mount host directories into container – data persists beyond container instance

• Kubernetes Container Orchestration• By default, will schedule containers on any node and your host directory probably won’t be there

• PetSets were recently introduced to solve this issue

18


Container networking challenges

• Containers communicating across hosts• Workaround: host only networking – container runs directly on host’s network interface

• Right way: Use Overlay Networking

• Set it up yourself with Weave (Hard)

• Use Kubernetes

• Use Docker Swarm

• Couchbase Server sensitive to change in IP address• Problem: restart a container and it gets a new IP address and tries to rejoin, cluster won’t recognize

• Workaround: configure with stable routable DNS names

Deployment Stages for Docker Cloud

23

1. Provisioning Nodes

2. Creating the Services

3. Deploying Containers

4. Scaling Services


Docker Cloud – (Dev Mode) 5 containers striped across 2 nodes

Docker Cloud Demo Recap

27

1. Start 2 Nodes (pre-demo)2. Start Couchbase Server Service with 2 Containers3. Configure Couchbase Server cluster4. Start Sync Gateway Service with 2 Containers5. Verify Sync Gateway6. Start HAProxy load balancer Service with 1 Container7. Verify Sync Gateway via HAProxy

Setup

1. Start new Node2. Scale Sync Gateway Service to add another container (3 total)3. Send Requests to HAProxy and verify logs in Sync Gateway Container 3
