FROM golangci/golangci-lint:latest as lint

# Set the Current Working Directory inside the container

# Copy the go.mod file and the rest of the application code
COPY go.mod ./

# Second stage: Use the official Golang image to run tests

# Set the final CMD to something minimal since we only needed to verify lint and tests during build
