This will ensure that the Docker process has enough permissions to create the configuration files in the mounted volumes.Local Directory, mounted in the /workspace dir as shown above.referenced in COPY commands.Īs build context we can use multiple sources It should contain the Dockerfile and any other files used to build the image, ie. If there is one aspect of docker which has caused us the most problems and for which we have been least able to find useful and detailed information on (which may just be our own fault), it is the interplay between containers, their users, bind mounted volumes and their permissions. Use the RUN instruction and the chown command to set the Docker volume. We need to provide the build context, containing the same files that we would put in the directory used when building a Docker image with a Docker daemon. Volume permissions van be changed by configuring the ownership within the Dockerfile. In Kubernetes we can manually create a pod that will do our Docker image build. ![]() v `pwd`/config.json:/kaniko/.docker/config.json:ro \ ![]()
