5. Docker in production 1/2
Quick deployment One of the key features of Docker is its ease of deployment.
Containers can be deployed quickly and managed using orchestration tools such as Docker
Swarm or Kubernetes.
Resource Management Resource management is a very crucial aspect in Docker systems.
Host machine resources such as CPU, memory, I/O, etc. are shared among the containers.
Over time, traffic spikes can happen and containers may face resource shortage.
Not having enough resources can cause containers to crash, thus disrupting the business.
Backup management Backups are vital for any live server. Disasters may strike any moment unexpectedly and an
unavailable website can lead to a loss of business income.
Having backups handy, helps to ensure business continuity and to minimize the downtime.
We maintain custom scripts to backup and restore the container data.

6. Docker in production 2/2
System security By default, Docker containers cannot be accessed from the external network. But when using docker in
production, many applications require to be accessed externally.
This is done by exposing Docker container ports by mapping them to the host machine’s port. But when ports
are exposed, security issues tag along with it.
Container monitoring Uptime and availability of production servers are crucial for online businesses. But high traffic, abusive users
or vulnerable applications can cause containers to crash.
To timely identify crashes and resolve them to ensure uptime, an effective Docker monitoring system such as
Zabbix
Image and
storage management
The main components of a Docker infrastructure are the data storage for storing the container data and the
image repository for saving Docker images.
In Docker, the data stored in the containers would be lost upon restart. To retain the data and to make the
system scalable, we configure persistent data storage using data volumes.
Many applications and services require customized Docker images for their business. Keeping these images
up-to-date with patches is crucial for Docker security.

8. Docker Familiarize
Production scale clustering and container scheduling for Docker
Docker compose
Docker machine
Docker nodes
Docker CLI
Docker container

9. Continuous Availability of Services
Docker is all about the high and reliable service to the end user.
Failover setup and sequential execution is at priority for the web applications in HA
setup.
Docker is all about resource utilization and saves good quantity of time used for
deployment.
Docker deployments are easier and cross platform.
Docker container porting is simplified with the docker hub.
Docker management is handled container management solutions.

10. Docker Swarm - Features
Docker-native clustering system
Pool of Docker hosts into a single, virtual host.
Multi-host networking.
Load balancing
Rolling updates
Secure by default
Cluster management integrated with Docker Engine
Define the desired state of the various services in the application stack.

11. Swarm mode CLI - Production
swarm init
swarm join
service create
service inspect
service ls
service rm
service scale
service ps
service update

12. Swarm – setup
AWS architecture supports terraform for the rolling update and integrates the
swarm mode configuration inside a AWS VPC.
• manager1
• worker1
• worker2

13. Service Automate – docker
Updating A Service Using Its Image Hash
Stack deployment is being made on automation
Docker service deployment with create and update commands
Lets look into the redis service deployment.

14. Demo
• We will have a simplified cluster formation in the AWS environment using Jenkins and terraform.

15. Kubernetes - Pods
Pod is one or more container
Ensures co-location / shared fate
Pods are scheduled, then do not move between nodes
Shared resources:
• Volumes
• IP/network
• Port Space
• CPU / Memory allocation

16. Label/selectors
Labels are arbitrary metadata
Attachable to nearly all API objects
Simple key=value pairs
Can be queried with selectors
Ex: release=stable, release=canary

17. Kubernetes AWS
Pods are created on EC2 and then the resources are shared.
Pods are working overlay networks.
We can see the service automate as similar to docker swarm cluster management.

18. Kubernetes – Demo
• Lets see the demo of working of cluster management with kubernetes.
