Step 1 – SSH Into Your Server

First, SSH into your server to access the Docker environment where WebLogic is running.

ssh user@your-server-ip

Step 2 – Add New Port to the Docker

Stop the running WebLogic container, commit changes, remove the old container, and run a new one with the updated port configuration:

docker stop weblogic
docker commit weblogic weblogic:updated
docker rm weblogic
docker run -d --name weblogic -p 7001:7001 -p 9002:9002 -p 7011:7011 -p 9011:9011 weblogic:updated

Step 3 – Retart WebLogic Container

Start the WebLogic container with the new ports open:

docker restart weblogic

Step 4 – Enter the Running Docker Container

Enter the running Docker container to configure WebLogic:

docker exec -it weblogic /bin/bash

Step 5 – Create a New Domain Directory

Create a directory for the new WebLogic domain:

mkdir -p /u01/oracle/user_projects/domains/webdomain

cd /u01/oracle/user_projects/domains/webdomain

Step 6 – Create the Domain Configuration Script

Create a Python script to configure the new WebLogic domain:

cat > create_domain.py << EOF
# Import WLST offline library
from weblogic.management.scripting.utils import WLSTInterpreter

# Load the default domain template
readTemplate("/u01/oracle/wlserver/common/templates/wls/wls.jar")

# Configure the Administration Server for HTTP
cd('Servers/AdminServer')
set('Name', 'AdminServer')
set('ListenAddress', '0.0.0.0')  # Set the specific IP address
set('ListenPort', 7011)                # Set port for HTTP

# Enable SSL and configure HTTPS port
create('AdminServer','SSL')
cd('SSL/AdminServer')
set('Enabled', 'True')
set('ListenPort', 9011)                # Set port for HTTPS

cd('/Security/base_domain/User/weblogic')
cmo.setPassword('welcome1')

# Define the path for the new domain
setOption('DomainName', 'webdomain')
setOption('OverwriteDomain', 'true')
setOption('ServerStartMode', 'prod')

# Write the domain configuration and close the template
writeDomain('/u01/oracle/user_projects/domains/webdomain')
closeTemplate()

# Exit WLST
exit()
EOF

Step 7 – Run the Domain Creation Script

Run the script to create the new WebLogic domain:

. /u01/oracle/oracle_common/common/bin/setWlstEnv.sh
/u01/oracle/oracle_common/common/bin/wlst.sh create_domain.py

Step 8 – Start the New Domain

Start the new domain by navigating to the new domain directory and using the startWebLogic script:

/u01/oracle/user_projects/domains/webdomain/startWebLogic.sh

It will ask for your WebLogic username and password. Provide the credentials you have used in Step 6. In our case, username is weblogic and the password is welcome1.

Enter username to boot WebLogic server:weblogic
Enter password to boot WebLogic server:welcome1

Step 9 – Access the Admin Console

Access the WebLogic Admin Console using the following URLs:

HTTP:

http://your-server-ip:7011/console

HTTPS:

https://your-server-ip:9011/console
