"no such file or directory" with Docker Scratch Image: Resolved

When using Docker's scratch image, you may encounter the error "no such file or directory" when executing a binary. This error often stems from the binary being dynamically linked to a library that does not exist in the image.

To rectify this issue, disable CGO (C Go):

RUN CGO_ENABLED=0 GOOS=linux GOARCH=amd64 go build \
    -ldflags="-w -s" -o $PROJ_BIN_PATH ./cmd/...

CGO links to system libraries, which can cause problems in a scratch image. By disabling CGO, you ensure that the binary is statically linked and does not depend on external libraries.

Additionally, you can verify the dynamic links in your binary using ldd:

docker build --target=0 -t your_go_image .
docker run -it --rm your_go_image ldd /$PROJ_NAME

This command will list any libraries that the binary is linked to. If ldd returns "not a dynamic executable," the binary is statically linked.

String Manipulation in Go: Mastering the 'strings' PackageMay 14, 2025 am 12:19 AM

Mastering the strings package in Go language can improve text processing capabilities and development efficiency. 1) Use the Contains function to check substrings, 2) Use the Index function to find the substring position, 3) Join function efficiently splice string slices, 4) Replace function to replace substrings. Be careful to avoid common errors, such as not checking for empty strings and large string operation performance issues.
