How to get a Go library and run it in Docker?-CodePudding

I have this simple Dockerfile:

FROM golang:1.16.6-buster
RUN wget -O - -q https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh | sh -s v1.45.2
RUN golangci-lint --version

When I build it, no matter how I change the second line above, I am always getting:

 > [3/3] RUN golangci-lint --version:
#6 0.331 /bin/sh: 1: golangci-lint: not found

What exactly I am doing wrong here?

If I try:

FROM golang:1.16.6-buster
RUN curl -s https://raw.githubusercontent.com/golangci/golangci-lint/master/install.sh\
    | sh -s v1.45.2

RUN bin/golangci-lint version

I get this detailed output:

This is how it worked finally. No binary was getting downloaded due to versions mismatch. I upgraded Go to 1.16 0 and the linter to 1.45.2. Also instead of wget I went for go install which works with this Go version. This got a binary downloaded in the default folder /bin and the CI job was fixed.

FROM golang:1.16.0-buster
RUN go install github.com/golangci/golangci-lint/cmd/[email protected]
RUN ./bin/golangci-lint --version
