How to Install Go in Alpine Linux Docker Images?

Installing Go in Alpine Linux Docker Images

To install Go in an Alpine Docker image, the following steps can be taken:

• Download the Go tar file from the official Go website.
• Extract the tar file using the command tar -C /usr/local -xzf go1.10.3.linux-amd64.tar.gz.

• Set the PATH environment variable to include the Go binary directory, as shown below:

  export PATH=$PATH:/usr/local/go/bin

  However, if the command go version returns "sh: go: not found," this indicates that some components may be missing.

To overcome this issue, you can consider using a multi-stage build approach. In this method, you can start with a Go base image, such as golang:1.13-alpine, and then copy the necessary files and directories from that image into your Alpine image. Here's an example:

FROM XXX
COPY --from=golang:1.13-alpine /usr/local/go/ /usr/local/go/
ENV PATH="/usr/local/go/bin:${PATH}"

By using this multi-stage build, you can ensure that your Alpine image includes all the required Go components and can be used to run Go programs effectively.
