Create an image with full Internet access

The Image Tool supports creating Linux based WebLogic container images, applying WebLogic patches, and creating WebLogic domains. It can be used with or without Internet access.

In this use case, the Image Tool will:

Start with a base-level operating system image (ghcr.io/oracle/oraclelinux:8-slim).
Update the image with the necessary packages for installing WebLogic Server.
Install Java and WebLogic Server.

Steps

Download these Java and WebLogic installers from the Oracle Software Delivery Cloud and save them in a directory of your choice, for example, /home/acmeuser/wls-installers:

fmw_12.2.1.3.0_wls_Disk1_1of1.zip
jdk-8u202-linux-x64.tar.gz
Use the Cache Tool to add the installers:
```
$ imagetool cache addInstaller --type jdk --version 8u202 --path /home/acmeuser/wls-installers/jdk-8u202-linux-x64.tar.gz
```
```
$ imagetool cache addInstaller --type wls --version 12.2.1.3.0 --path /home/acmeuser/wls-installers/fmw_12.2.1.3.0_wls_Disk1_1of1.zip
```
Note: The value of the version must be a valid WebLogic Server version number. This version number is used to verify and find the correct patch file to download from Oracle Support. The format of the version is a 5 digits tuple, separated by period. For example, 12.2.1.3.0 12.1.3.0.0
Create the image using the Create Tool commands. For example:

$ imagetool create --tag wls:12.2.1.3.0 --latestPSU --version 12.2.1.3.0 --user  username@mycompany.com --passwordEnv MYPWD

Where --user --passwordEnv provides the credentials for a user who is entitled to download patches from Oracle Support.

NOTE: You can provide the password in one of three ways:

Read from STDIN --password
Environment variable --passwordEnv
File containing the password --passwordFile

You will see the Docker command output as the tool runs:
