I installed centos 7 (atomic) in AWS using ami-114f5c7b, I tried to update and do other things but it's telling me "yum command not found." Please help.
Cause Project Atomic use Ostree model for packaging, this make yum or dnf command unavailable. if you prefer package customize please consult
Otherwise choose normal distro ( Centos, Fedora ) or choose PhotonOS instead , They have tdnf ( small dnf tool installed ) and you can still use rpm-ostree as well.
