Install wget in Docker in Codebuild - docker

Question

I'm using the serverless framework to build an application that is using a docker image. In the Dockerfile I have this command
RUN yum install wget -y
RUN wget https://julialang-s3.julialang.org/bin/linux/x64/1.8/julia-1.8.2-linux-x86_64.tar.gz
which works fine locally (windows) and on an Linux EC2 however when I run this through my build on codebuild (Image: aws/codebuild/amazonlinux2-x86_64-standard:4.0 with runtime-versions: docker 20) I get an error
Step 12/19 : RUN yum install wget -y
