PreBuilt Oracle Database 18c with Docker

In this post, we can use Docker service to pull the prebuilt Oracle Database 18c. Docker must be installed and running for this feature prerequisite.

In your VM or Bare Metal, check the status and version of Docker if it is installed.

[root@docker ~]# docker info
[root@docker ~]# docker version

[root@docker ~]#

To Install Docker on your machine, please go to https://docs.docker.com/install/.

As Docker is running, now we need to pull the image from Docker Hub which already created by OracleHelp Team.

[root@docker ~]# docker images

[root@docker ~]#

Note: Make sure, there must be sufficient space in the root file system.

After Image has successfully pulled, now we will connect with Docker Container to log in.

[root@docker ~]# docker images
REPOSITORY                        TAG                 IMAGE ID            CREATED             SIZE

[root@docker ~]# docker run -it dockerhelp/docker-oracle-ee-18c
[root@c42c43a508fe /]#

At this moment, Oracle 18c Home and Default Database are already configured.

Database Name: ORCL18 with one pluggable database PDB18C has default password Welcome_1.

To start the Database and configure listener & TNS file, run the below script inside the container.

[root@c42c43a508fe /]# sh post_install.sh
