1. Clone the repository containing the Dockerfile and related scripts.
2. Navigate to the directory containing the Dockerfile.
3. Build the Docker image using the following command:

docker build -t <image_name> .

Selecting Tool Versions

This Docker image allows you to select specific versions of the tools included. The versions are defined as build arguments in the Dockerfile. To select a particular version for a tool, follow these steps:

1. Identify the name of the tool and its corresponding build argument in the Dockerfile. Here are the tools and their associated build arguments:

   • kubectl: KUBECTL_VERSION
   • kustomize: KUSTOMIZE_VERSION
   • Helm: HELM_VERSION
   • kubeconform: KUBECONFORM_VERSION

2. When building the Docker image using the docker build command, provide the desired versions as build arguments using the --build-arg flag. For example:

#Override kubectl and kustomize versions only
docker build -t k8s-ci-cd \
  --build-arg KUBECTL_VERSION=1.29.1 \
  --build-arg KUSTOMIZE_VERSION=3.5.4 \
