Just to summarize what you can do if your Docker image build context too large:

• make sure you don't have unused files in the context (unused files - those that still untouchable during image building);
• add unused files and/or directories to .dockerignore (as mentioned here);
• make sure you specify the right folder as an image build context (as mentioned here);
• try to use BuildKit with DOCKER_BUILDKIT=1 (as mentioned here);
• try to split your project into smaller parts to optimize content of build context;
• if you have a complex project you may want to manually collect all necessary files in separate folder before build and use it as a build context for a specific image.
