feldmannjr/nexus3 repository overview

⁠SonaType Nexus Repository Manager 3 Docker Image

Image based on openjdk-8 with the focus in automatization

⁠How it works

I was unable to find a way to automatize all the installation without to manually uploading the configuration scripts after the installation.
This image runs a process that waits for the repository startup, than upload the scripts found in /etc/nexus-init.d/ directory.

⁠How to use

Just copy the .groovy scripts to /etc/nexus-init.d/ example of instruction in Dockerfile
ADD examples/src/main/groovy/changePassword.groovy /etc/nexus-init.d/
Look at script examples HERE⁠.

⁠Using Env Variables in Scripts

Because the nexus groovy container blocks the import of java.lang.System, i was unable to find a way to access env variable in scripts.
To fix this issue i am preprocessing variables in the groovy scripts with the consequence of breaking default groovy string interpolation, you can still use groovy interpolation, but the dollar char must be escaped.

⁠Example

// assuming there is an env variable TEST with value of "12345"
def TEST = "Testing..."

println "${TEST}"
// Prints 12345

println "\${TEST}"
// Prints Testing...

println "\\${TEST}"
// Prints ${TEST} 

⁠Environment Variables

⁠NEXUS_ADMIN_PASSWORD

The password for the admin user. Default: admin123

⁠NEXUS_SCRIPT_SEARCH_DIR

Where the watcher will scan for groovy scripts. Default: /etc/nexus-init.d

⁠Persist Data

All the data is stored in /nexus-data, just create a volume.
Example: docker run -it -p 8081:8081 -v ./nexus_data:/nexus-data feldmannjr/nexus3
