Source Build Guide - 0.18 and Up

For organizations who prefer to build the software directly from source code, they can compile the Altinity Kubernetes Operator and install it into a Docker container through the following process. The following procedure is available for versions of the Altinity Kubernetes Operator 0.18.0 and up.

Binary Build

Binary Build Requirements

• go-lang compiler: Go.
• Go mod Package Manager.
• The source code from the Altinity Kubernetes Operator repository. This can be downloaded using git clone https://github.com/altinity/clickhouse-operator.

Binary Build Instructions

1. Switch working dir to clickhouse-operator.

2. Link all packages with the command: echo {root_password} | sudo -S -k apt install -y golang.

3. Build the sources with go build -o ./clickhouse-operator cmd/operator/main.go.

This creates the Altinity Kubernetes Operator binary. This binary is only used within a kubernetes environment.

Docker Image Build and Usage

Docker Build Requirements

• kubernetes: https://kubernetes.io/
• docker: https://www.docker.com/
• Complete the Binary Build Instructions

Install Docker Buildx CLI plugin

1. Download Docker Buildx binary file releases page on GitHub

2. Create folder structure for plugin

   mkdir -p ~/.docker/cli-plugins/
   

3. Rename the relevant binary and copy it to the destination matching your OS

   mv buildx-v0.7.1.linux-amd64  ~/.docker/cli-plugins/docker-buildx
   

4. On Unix environments, it may also be necessary to make it executable with chmod +x:

   chmod +x ~/.docker/cli-plugins/docker-buildx
   

5. Set buildx as the default builder

   docker buildx install
   

6. Create config.json file to enable the plugin

   touch ~/.docker/config.json
   

7. Create config.json file to enable the plugin

   echo "{"experimental": "enabled"}" >> ~/.docker/config.json
   

Docker Build Instructions

1. Switch working dir to clickhouse-operator

2. Build docker image with docker: docker build -f dockerfile/operator/Dockerfile -t altinity/clickhouse-operator:dev .

3. Register freshly build docker image inside kubernetes environment with the following:

   docker save altinity/clickhouse-operator | (eval $(minikube docker-env) && docker load)
   

4. Install the Altinity Kubernetes Operator as described in either the Basic Build or Custom Build.
