How to add Docker images to private registry

The following instructions show how to pull Docker containers from public Docker registries and push them to a private Docker registry.

5. Push images to private Docker registry

Prerequisites

1. If you need to create a private docker registry, see WHATIS - docker registry server.

Build docker images

🤔 Optional: Build any Docker images that aren't on a public Docker registry.

1. Build Senzing "helper" Docker images. Example:

   docker build --tag senzing/mysql        https://github.com/senzing-garage/docker-mysql.git#main
   docker build --tag senzing/mysql-init   https://github.com/senzing-garage/docker-mysql-init.git#main
   

Identify docker images

1. 🤔 Optional: Specify versions of Docker images. Example:

   curl -X GET \
       --output /tmp/docker-versions-stable.sh \
       https://raw.githubusercontent.com/Senzing/knowledge-base/main/lists/docker-versions-stable.sh
   source /tmp/docker-versions-stable.sh
   

2. ✏️ List docker images in DockerHub in an environment variable. Add or delete Docker images from the list. For extensive list, see docker-image-names.sh Example:

   export DOCKER_IMAGE_NAMES=(
       "senzing/senzingapi-runtime:${SENZING_DOCKER_IMAGE_VERSION_SENZINGAPI_RUNTIME:-latest}"
   )
   

Pull images from public Docker registries

1. Add docker images to local docker repository. Example:

   for DOCKER_IMAGE_NAME in ${DOCKER_IMAGE_NAMES[@]};\
   do \
     docker pull ${DOCKER_IMAGE_NAME}; \
   done
   

Push images to private Docker registry

1. ✏️ Identify the URL of the private Docker registry. Example:

   export DOCKER_REGISTRY_URL=my.docker-registry.com:5000

2. Push Docker images to private docker registry. Example:

   for DOCKER_IMAGE_NAME in ${DOCKER_IMAGE_NAMES[@]};\
   do
     docker tag  ${DOCKER_IMAGE_NAME} ${DOCKER_REGISTRY_URL}/${DOCKER_IMAGE_NAME};
     docker push ${DOCKER_REGISTRY_URL}/${DOCKER_IMAGE_NAME};
     docker rmi  ${DOCKER_REGISTRY_URL}/${DOCKER_IMAGE_NAME};
   done
