Step 1: Start docker container

docker-compose up -d

Step 2: Get your Server ID

Access to http://localhost:8080 then follow installation process, you can see your Server ID after few steps

Step 3: Get your decoder file

Copy decoder file from container, xxx is version of decoder file

docker cp confluence:/opt/atlassian/confluence/confluence/WEB-INF/lib/atlassian-extras-decoder-xxx.jar /local/folder/

Step 4: Rename decoder file

We need this file to generate license key, now keygen work on windows system only so you have to download this file to local device to generate license

atlassian-extras-2.4.jar

Step 5: Access container with root user and rename / remove decoder file

docker exec -it -u 0 {CONTAINER_ID} bash

then

mv /opt/atlassian/confluence/confluence/WEB-INF/lib/atlassian-extras-decoder-xxx.jar /opt/atlassian/confluence/confluence/WEB-INF/lib/atlassian-extras-decoder-xxx.jar.bak

Step 6: Path decoder file with keygen

Run keygen (on local windows device) by following command

Now keygen works on windows system only and you need java JDK to run keygen

Use your Server ID from step 1 and atlassian-extras-2.4.jar from step 2

confluence_keygen.jar can be found inside /crack/iNViSiBLE

java -jar confluence_keygen.jar

Step 7: Change decoder file name back to original

Keygen will update your decoder file, you need to save new decoder file to its location inside container

Step 8: Move new decoder file back to container

docker cp /local/folder/atlassian-extras-decoder-xxx.jar confluence:/opt/atlassian/confluence/confluence/WEB-INF/lib/

Step 9: Restart container and setup confluence

docker-compose restart

Step 10: Continue installation instruction with generated key
