Important Considerations

When using dploy, there are a few important considerations to keep in mind.

.dockerignore File

Always create a .dockerignore file for your project. This file should list all the files and directories that should be excluded when building the Docker image. Here's an example:

# .dockerignore

# Exclude node_modules since it is too large to be copied into the Docker image.
# Install dependencies in the Dockerfile instead.
node_modules

# For better caching, exclude these files if using `COPY . .` in the Dockerfile.
dploy.toml
Dockerfile
.dockerignore

# Exclude macOS-specific files
.DS_Store

Using COPY file* ./ in the Dockerfile

When copying files with a glob expression in the Dockerfile, it's crucial to end the destination path with a /. According to Docker's documentation:

When using COPY with more than one source file, the destination must be a directory and end with a /

If you omit the / at the end, the process may fail silently during the Docker image build.

Using dploy with colima

If you are using colima, add the following line to your .zshrc or .bashrc file:

export DOCKER_HOST=unix://$HOME/.colima/default/docker.sock
