RUN yum in Docker file not working, but yum it's working inside the container
11,503
if I were you I would check the following things:
- Try Centos7 image and run the same commands
- Try to run
yum clean all
before running update so it should look like thisRUN yum clean all && yum update -y
- Check the network limitation in DNS resolving and you can check this link for guide and also this guide from docker to configure custom network
- Also check the firewall configuration on the Host machine

I'm trying to build a container from amazonlinux (fedora based).
If I build the image and I enter into the container the yum command works normally. However if I put the yum command inside the Dockerfile, it doesn't. It seems that fails to contact the repository
Dockerfile
FROM amazonlinux RUN yum update -y
running: sudo docker build .
Sending build context to Docker daemon 3.072kB Step 1/2 : FROM amazonlinux ---> df7d0b6ddeee Step 2/2 : RUN yum update -y ---> Running in 14e4e4bad5b1 Loaded plugins: ovl, priorities
result, several https tried and in the end:
...URLError: (28, 'Resolving timed out after 5516 milliseconds') Trying other mirror... The command '/bin/sh -c yum update -y' returned a non-zero code: 1
