Small Go image to use when CGO isn't needed.
- Runs as a non-root user by default.
- CA certificates are pulled from the Common CA Database.
- Time Zone database is pulled from the Go image (
zoneinfo.zip).
- Less than 1MB.
- Home and temp directories are available.
- You must use
CGO_ENABLED=0 to build, because no OS libraries are present.
The image is tagged with the major Go version because that indicates which zoneinfo.zip is included.
docker pull ancientlore/goimg:1.20
Presumably you would put your Go binary into /usr/bin or /bin. A sample Dockerfile might be:
FROM golang:1.20 as builder
COPY . /go/test
WORKDIR /go/test
RUN CGO_ENABLED=0 go build -o /go/bin/test
FROM ancientlore/goimg:1.20
COPY --from=builder /go/bin/test /usr/bin/test
CMD [ "/usr/bin/test"]
