How to create a simple Docker container with Go utilities installed

php editor Zimo will introduce you how to create a simple Docker container and install Go utilities in it. Docker is a popular containerization platform that helps developers package applications with their dependencies for easy deployment and running in different environments. Go is a fast, efficient programming language with many excellent utilities available. This article will show you how to use Docker to create a simple container with Go utilities installed so that you can quickly start using a Go development environment. let's start!

Question content

I have been exploring docker capabilities in order to create simple containers with some go utilities installed. I need to create an image with thegosecandgovulncheckutilities installed so that I can run them on my code in the container. My little attempt produced the following results:

# syntax=docker/dockerfile:1 from golang:1.19-alpine workdir /app env go111module=on # copying my code to check copy go.mod ./ copy go.sum ./ run go mod download copy *.go ./ run go build -o /docker-gs-ping run apk add --no-cache git run go install github.com/securego/gosec/v2/cmd/gosec@latest run go install golang.org/x/vuln/cmd/govulncheck@latest expose 8080 cmd [ "gosec ./..." ]

Running the container results in an error:

docker: Error response from daemon: failed to create shim task: OCI runtime create failed: runc create failed: unable to start container process: exec: "gosec ./...": stat gosec ./...: no such file or directory: unknown. ERRO[0000] error waiting for container: context canceled

Looks like I need to specify the path to the installed utility, but I can't get it to work

Workaround

This is not a path issue; it's a path issue. The problem is the syntax you are using in your dockerfile'scmdstatement. You are using the json format of thecmdstatement; the first parameter in the json list is the name of the command to run. You have asked docker to run a command namedgosec ./...which of course does not exist.

You need to split it into multiple list items:

cmd [ "gosec", "./..." ]

Alternatively, you can use the shell form of thecmdcommand:

CMD gosec ./...

When you start a container, any of them will rungosec.
