  • Open Source •Container Technology • Portable standard • Runs on Linux (Microsoft, MacOS, Solaris) • Quickly scale • Improve it efficiency • SIMPLY SHARE APPLICATIONS
• 3.
  Containers are anapp level construct VMs are an infrastructure level construct to turn one machine into many servers
• 4.
  Docker is nota lightweight VirtualBox - it's about isolation. - Containers run on Linux kernel of host. Use de same kernel - Containers are visible on host. - Containers can’t access to host.

  Speed • No OSto boot = applications online in seconds Portability • Less dependencies between process layers = ability to move between infrastructure Efficiency • Less OS overhead • Improved VM density

  Dockerfile File like ascript for build Docker images. Image The basis of a Docker container. The content at rest. Container The image when it is ‘running.’ The standard unit for app service. Docker Engine The software that executes commands for containers. Networking and volumes are part of Engine. Can be clustered together. Registry Stores, distributes and manages Docker images. Control Plane Management plane for container and cluster orchestration.

  • Isolated runtimeof Docker image (Instance) • Starts up in milliseconds • Sandboxing uses Linux namespaces and cgroups (RAM, CPU, filesystem) isolated part of your Linux • Open Container Standard / Linux Foundation $ docker run -d –p 8080:9999 oracledatabase

  But … Oracle Databaseon Docker ?
• 19.
  • It ispossible • Completely automated • Support 11g and 12c • Database is persistent (Share a host filesystem) • Works like a normal database • Customizable • No OS Depended • Supported by Oracle • Prerequisite: Docker installed
• 20.
  Some Oracle databasefeatures are not supported in this Docker image release: • Automatic Memory Management (AMM) • Multiples Oracle Homes • Oracle Data Guard • Multiples instances on the container • Oracle Grid Infrastructure

  1. Login inDocker Store (create Docker account before) $ docker run -d -it --name <Oracle-DB> store/oracle/database- enterprise:12.2.0.1 2. Run Oracle Database Container. Where Oracle-DB is the container name $ docker login 3. Connecting to the Database Container. The default password to connect to the database with sys user is Oradoc_db1 $ docker exec -it <Oracle-DB> bash -c "source /home/oracle/.bashrc; sqlplus /nolog" See details: https://store.docker.com/images/oracle-database-enterprise-edition/plans/08cf8677-bb8f-453c-b667- 6b0c24a388d4?tab=instructions

  $ docker build--force-rm=true --no-cache=true -t oracle/database:12.2.0.1-ee -f Dockerfile.ee . 1. Download the Github repository. https://github.com/oracle/docker-images 2. On your PC Extract Repository 3. Copy Oracle Software for Linux x64 in the folder appropriate to version. e.g. For Oracle Database 12.2 copy to folder ./docker-images/OracleDatabase/dockerfiles/12.2.0.1/ 4. Build Image e.g. Build Image for Oracle Database 12.2 Enterprise Edition
