Setting up Local Nexus Artefact Repository

5. Retrieve the Admin Password

Nexus generates an admin password on first startup. Retrieve it using:

docker exec -it nexus cat /nexus-data/admin.password

Use this password to log in with the username admin.

6. Change the Admin Password

Upon first login, you’ll be prompted to change the default password. Choose a strong password for security.

7. Configure a Repository (Example: Maven)

1. Navigate to Repositories in the Nexus UI.
2. Click Create Repository.
3. Choose Maven (hosted).
4. Set Repository Name (e.g., maven-releases).
5. Click Create Repository.

Repeat for other repository types as needed (Docker, NPM, etc.).
