Getting started with docker
0 likes60 views
To get started with Docker, install the Docker Desktop application and make a Docker ID. For Java deployments, package code into a JAR/WAR/EAR file that can run on the host JVM. With Docker, applications are packaged into images that follow a standard format and are run by the Docker engine instead of a full virtual machine and guest OS, reducing memory usage. Docker releases new major versions quarterly and each is supported for one year.

- 1. Getting Started with Docker
- 2. Getting Started Install Docker Community Version Install Java Install Maven Start Docker Desktop Application Make a Docker ID
- 3. Java Deployments Package Code into a single file: JAR/WAR/EAR JVM present on Host OD JVM understands the bytecode
- 4. Docker Deployments Package application into an Image Image follows a standard format Docker engine/host understands the Docker Image
- 5. What are VMs? Use Hypervisor which can support different OS from Host Example: Type 2 Hypervisor like Virtual Box Each Guest OS needs complete memory requirements
- 6. How is Docker different? Docker is an App Delivery Technology No full blown OS but Docker Engine has a minimal OS Instead of 1GB RAM in case of Guest OS, now memory need is only 120MB
- 7. Docker Releases 1 major release every quarter, starting from March 2017 Each major release supported officially for 1 year
- 8. Installing Docker Library Use simple commands: docker run -p 6379:6379 redis
- 9. Hello from Docker docker run hello-world
- 10. Using the test application
- 11. More in coming sessions...
