41106ade6SVladimir Kotal# A Docker container for OpenGrok
51106ade6SVladimir Kotal
61106ade6SVladimir Kotal## OpenGrok from official source
71106ade6SVladimir Kotal
81106ade6SVladimir KotalBuilt from official source: https://github.com/oracle/opengrok/releases/
91106ade6SVladimir Kotal
101106ade6SVladimir KotalYou can learn more about OpenGrok at http://oracle.github.io/opengrok/
111106ade6SVladimir Kotal
121106ade6SVladimir KotalThe container is available from DockerHub at https://hub.docker.com/r/opengrok/docker/

141106ade6SVladimir Kotal## When not to use it
151106ade6SVladimir Kotal
16*bc2f6de0SVladimir KotalThis image is simple wrapper around OpenGrok environment. It is basicallyt a small appliance. The indexer and the web container are **not** tuned for large workloads.
17*bc2f6de0SVladimir Kotal
181106ade6SVladimir KotalIf you happen to have one of the following:
191106ade6SVladimir Kotal  - large source data (e.g. [AOSP](https://en.wikipedia.org/wiki/Android_Open_Source_Project) or the like)
201106ade6SVladimir Kotal  - stable service
211106ade6SVladimir Kotal  - Source Code Management systems not supported in the image (e.g. Perforce,
221106ade6SVladimir Kotal    Clearcase, etc.)
23*bc2f6de0SVladimir Kotal  - need for authentication/authorization
24*bc2f6de0SVladimir Kotalthen it is advisable to run OpenGrok standalone or construct your own Docker
251106ade6SVladimir Kotalimage based on the official one.

27f70822c2SVladimir Kotal## Additional info about the image
281106ade6SVladimir Kotal
291106ade6SVladimir Kotal* Tomcat 9
301106ade6SVladimir Kotal* JRE 8 (Required for Opengrok 1.0+)
311106ade6SVladimir Kotal* Configurable mirroring/reindexing (default every 10 min)
321106ade6SVladimir Kotal
331106ade6SVladimir KotalThe mirroring step works by going through all projects and attempting to
341106ade6SVladimir Kotalsynchronize all its repositories (e.g. it will do `git pull` for Git
351106ade6SVladimir Kotalrepositories).

37ab135123SVladimir Kotal### Indexer logs
38ab135123SVladimir Kotal
391106ade6SVladimir KotalThe indexer/mirroring is set so that it does not log into files.
401106ade6SVladimir KotalRather, everything goes to standard (error) output. To see how the indexer
411106ade6SVladimir Kotalis doing, use the `docker logs` command.

591106ade6SVladimir Kotal## How to run
601106ade6SVladimir Kotal
611106ade6SVladimir Kotal### From DockerHub
621106ade6SVladimir Kotal
631106ade6SVladimir Kotal    docker run -d -v <path/to/your/src>:/opengrok/src -p 8080:8080 opengrok/docker:latest
641106ade6SVladimir Kotal
651106ade6SVladimir KotalThe container exports ports 8080 for OpenGrok.
661106ade6SVladimir Kotal
671106ade6SVladimir KotalThe volume mounted to `/opengrok/src` should contain the projects you want to make searchable (in sub directories). You can use common revision control checkouts (git, svn, etc...) and OpenGrok will make history and blame information available.
681106ade6SVladimir Kotal
691106ade6SVladimir KotalBy default, the index will be rebuild every ten minutes. You can adjust this
701106ade6SVladimir Kotaltime (in minutes) by passing the `REINDEX` environment variable:
711106ade6SVladimir Kotal
721106ade6SVladimir Kotal    docker run -d -e REINDEX=30 -v <path/to/your/src>:/opengrok/src -p 8080:8080 opengrok/docker:latest
731106ade6SVladimir Kotal
741106ade6SVladimir KotalSetting `REINDEX` to `0` will disable automatic indexing. You can manually trigger an reindex using docker exec:
751106ade6SVladimir Kotal
761106ade6SVladimir Kotal    docker exec <container> /scripts/index.sh
771106ade6SVladimir Kotal
781106ade6SVladimir KotalSetting `INDEXER_OPT` could pass extra options to opengrok-indexer. For example, you can run with:
791106ade6SVladimir Kotal
801106ade6SVladimir Kotal    docker run -d -e INDEXER_OPT="-i d:vendor" -v <path/to/your/src>:/opengrok/src -p 8080:8080 opengrok/docker:latest
811106ade6SVladimir Kotal
821106ade6SVladimir KotalTo remove all the `*/vendor/*` files from the index. You can check the indexer options on
831106ade6SVladimir Kotal
841106ade6SVladimir Kotalhttps://github.com/oracle/opengrok/wiki/Python-scripts-transition-guide
851106ade6SVladimir Kotal
861106ade6SVladimir KotalTo avoid the mirroring step, set the `NOMIRROR` variable to non-empty value.
871106ade6SVladimir Kotal
881106ade6SVladimir Kotal## OpenGrok Web-Interface
891106ade6SVladimir Kotal
901106ade6SVladimir KotalThe container has OpenGrok as default web app installed (accessible directly from `/`). With the above container setup, you can find it running on
911106ade6SVladimir Kotal
921106ade6SVladimir Kotalhttp://localhost:8080/
931106ade6SVladimir Kotal
941106ade6SVladimir KotalThe first reindex will take some time to finish. Subsequent reindex will be incremental so will take signigicantly less time.
951106ade6SVladimir Kotal
961106ade6SVladimir Kotal### Build image locally
971106ade6SVladimir Kotal
981106ade6SVladimir KotalIf you want to do your own development, you can build the image yourself:
991106ade6SVladimir Kotal
1006670a14aSVladimir Kotal    mvn -DskipTests=true clean package && \
1011106ade6SVladimir Kotal        docker build -t opengrok-dev .
1021106ade6SVladimir Kotal
1031106ade6SVladimir KotalThen run the container:
1041106ade6SVladimir Kotal
1051106ade6SVladimir Kotal    docker run -d -v <path/to/your/src>:/opengrok/src -p 8080:8080 opengrok-dev
1061106ade6SVladimir Kotal
1071106ade6SVladimir Kotal## Inspecting the container
1081106ade6SVladimir Kotal
1091106ade6SVladimir KotalYou can get inside a container using the [command below](https://docs.docker.com/engine/reference/commandline/exec/):
1101106ade6SVladimir Kotal
