Building an all-in-one GitLab Docker image locally
The GitLab all-in-one Docker image uses Ubuntu 16.04 package created by
omnibus-gitlab
under the hood. The files required for building Docker image
can be found inside the Docker
directory of omnibus-gitlab
repository,
except RELEASE
file which needs to be compiled manually, as described below.
RELEASE file
The details of the version of the package being used is stored in a file named
RELEASE
. To build your own Docker image, you should create this file with
contents similar to the following
RELEASE_PACKAGE=gitlab-ee
RELEASE_VERSION=13.2.0-ee
DOWNLOAD_URL=https://example.com/gitlab-ee_13.2.00-ee.0_amd64.deb
Here, RELEASE_PACKAGE
specifies whether the package is a CE one or EE one.
RELEASE_VERSION
specifies the version of the package (13.2.0-ee
,
12.9.2+rfbranch.150270.c43b3273-0
, etc.). DOWNLOAD_URL
specifies the URL
where that package can be downloaded from.
NOTE Note: We’re looking at improving this situation, and using locally available packages in issue #5550.
Building the Docker image
To build the Docker image after populating the RELEASE
file:
cd docker
docker build -t omnibus-gitlab-image:custom .
The image will be built and tagged as omnibus-gitlab-image:custom
.
