In order to get Docker to recognize the GPU, we need to make it aware of the GPU drivers. We do this in the image creation process. This is when we run a series of commands to configure the environment in which our Docker container will run. The "brute force approach" to ensure Dock...
As you may already know,Dockeris an amazing tool for collaborative programming work, allowing us to work in a virtually identical environment, regardless of the operating system we are on. In a previous article we learned how to create our own Docker images to test and distribute our applicatio...
By design (for better or worse), Docker doesn’t allow setting arbitrary environment variables during the Docker build process: that is only possible when running Containers after the Image is built. The rationale for this is that Dockerfiles should be fully portable and not tied to any ...
In themongoservice, use environment variables to set the credentials for the MongoDB database, and reference the secrets stored in the mounted volume.
