onos-config : make images failing on CentOS 8

[Bhanupriya03]

We tried making images of onos-config on CentOS 8. Please have a look at the error we got :

[root@localhost onos-config]# make images

Please suggest how to install 'apk' and libc6-compat in CentOS 8

[gab-arrobo]

The error here is not related to your OS because what you are doing is building the Docker image. Moreover, APK is the Alpine's package manager, which is specific for the image you are pulling (Alpine).
You can try these steps in your system:

$ docker pull alpine:3.13
$ docker container run --name=alpine -it alpine:3.13 apk add libc6-compat

The output of the last command should look like below, which is the same step where you see the error when using make images

fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/main/x86_64/APKINDEX.tar.gz
fetch https://dl-cdn.alpinelinux.org/alpine/v3.13/community/x86_64/APKINDEX.tar.gz

Hi Gab-Arrobo

Thank you so much for your response !!!

We tried the above mentioned commands and please have a look at the output for both :

It says 'Permission Denied' on fetching apline's APK tars. We also tried 'yum update ca-certificates' as we thought this is the certificate issue. But we got no success for the second command. Please suggest what should be done next to make successful image of onos-config.
