Therefore, instead of creating\nyour own base image from scratch, you can use the official Go image that already\nhas all necessary tools and libraries to compile and run a Go application.\n\n> [!NOTE]\n>\n> If you are curious about creating your own base images, you can check out the following section of this guide: [creating base images](/manuals/build/building/base-images.md#create-a-base-image).\n> Note, however, that this isn't necessary to continue with your task at hand.\n\nNow that you have defined the base image for your upcoming container image, you\ncan begin building on top of it.\n\nTo make things easier when running the rest of your commands, create a directory\ninside the image that you're building. This also instructs Docker to use this\ndirectory as the default destination for all subsequent commands. This way you\ndon't have to type ou\n```\n\nBounded code example (external data; do not execute automatically):\n```text\nUsually the very first thing you do once you’ve downloaded a project written in\nGo is to install the modules necessary to compile it. Note, that the base image\nhas the toolchain already, but your source code isn't in it yet.\n\nSo before you can run `go mod download` inside your image, you need to get your\n`go.mod` and `go.sum` files copied into it. Use the `COPY` command to do this.\n\nIn its simplest form, the `COPY` command takes two parameters. The first\nparameter tells Docker what files you want to copy into the image. The last\nparameter tells Docker where you want that file to be copied to.\n\nCopy the `go.mod` and `go.sum` file into your project directory `/app` which,\nowing to your use of `WORKDIR`, is the current directory (`./`) inside the\nimage. Unlike some modern shells that appear to be indifferent to the use of\ntrailing slash (`/`), and can figure out what the user meant (most of\n```\n\nBounded code example (external data; do not execute automatically): …\n\nAttribution: Adapted from Docker Documentation under Apache-2.0.
