Building Custom Docker Images
The docker build tool kit could be found on OPSWAT Portal - Products - Utilities
The build tool kit includes the following files:
Dockerfile- main script for building the docker image.entrypoint.sh- startup script that runs when the container starts.patch.sh- utility script for string replacing in the file, needed for building docker image.systemctl.py(only applicable to CentOS) - the replacement for systemctl, needed for non-privileged container.
To build the image, just run the following command:
docker build -t <image_name[:tag]> [--build-arg VERSION=<version>] <build-kit_path><image_name[:tag]>- name of your built image with optional tag (e.g.latest).--build-arg VERSION=<version>- the desired MetaDefender ICAP Server version to be downloaded from OPSWAT. If obmitted then a local installer will be used, the installer should be placed in the working directory with name is formatted /mdicapsrv/mdicapsrv-*.rpm or .deb (configurable in the Dockerfile).<build-kit_path>- relative path to your build-kit which contains Dockerfile.
For example:
docker build -t mdicapsrv:centos --build-arg VERSION=4.13.0RC .In Dockerfile, there are some environment variables that can be modified for various use cases. You should modify the environment variables before building the MetaDefender ICAP Server docker image.
