Describe minikube setup for evaluation The documentation that far assumed that the user has a Kubernetes cluster in the cloud available. For initial evaluation of the helm charts, it would be practical to be able to test them on a local machine. This change provides documentation and sample configuration files to install a gerrit-master and gerrit-slave setup on a local machine using Minikube. Change-Id: I1eeb07401855910cca6c048e936e44c76ca6238a
Images to run a Gerrit master and slave setup based on the latest stable-2.12 Gerrit build.
To build all images, the
build-script in the root directory of the project can be used:
If a specific image should be build, the image name can be specified as an argument. Multiple images can be specified at once:
./build gerrit-slave git-gc
The build-script usually uses the
latest-tag to tag the images. By using the
--tag TAG-option, a custom tag can be defined:
./build --tag test
The build script will in addition tag the image with the output of
git describe --dirty.
The single component images inherit a base image. The
Dockerfile for the base image can be found in the
./base-directory. It will be automatically built by the
./build-script. If the component images are built manually, the base image has to be built first with the target
base:latest, since it is not available in a registry and thus has to exist locally.
The publish script in the root directory of the project can be used to push the built images to the configured registry. To do so, log in first, before executing the script.
docker login <registry>
To configure the registry and image version, the respective values can be configured via env variables
TAG. In addition, these values can also be passed as command line options named
--tag in which case they override the values from env variables:
<component-name> is one of:
--update-latest-flag will also update the images tagged
latest in the repository:
./publish --update-latest <component-name>
Assuming a Gerrit site already exists, is located at
/path/to/gerrit-slave and owned by the
gerrit-user defined in the docker image (default
UID: 1000) run the following command for each image in the directories containing the respective docker image:
./start /path/to/gerrit-slave <component-name>
<component-name> is one of:
If a specific version of the image should be used, the
--tag TAG-option can be used to provide the image tag:
./start /path/to/gerrit-slave --tag d4fad48 <component-name>
or define the tag as an env variable:
export TAG=d4fad48 ./start /path/to/gerrit-slave <component-name>
To detach the running container from the shell, use the
./start --detach /path/to/gerrit-slave <component-name>
Currently, java is installed under
/usr/lib/jvm/java-8-openjdk-amd64/jre. Therefore, make sure that
container.javaHome is set to that path in the
javaHome = /usr/lib/jvm/java-8-openjdk-amd64/jre
The mysql-replication-init docker image is only required for setting up the Gerrit slave on Kubernetes. If deploying the Gerrit slave outside of Kubernetes, it can be ignored.
These Helm charts can be used to install a Gerrit cluster consisting of a Gerrit master and a Gerrit slave on a Kubernetes cluster.
To evaluate and test the helm-charts, they can be installed on a local machine running Minikube. Follow this guide to get a detailed description how to set up the Minikube cluster and install the charts.
Currently this deployment uses NFS, some options:
