Consistent DNS name resolution for virtual machines and containers

When developing on microservices, developers need to run a mix of software. Some of them running in containers, others in virtual machines, some others in the cloud and the rest on the developer’s workstation. Microservices having a lot of connections between themselves in addition to technologies such as TLS or OpenID Connect implies DNS names to be consistent. Consistent DNS names means that no matter if a client on the developer workstation, on a VM or on a container, trying to reach a server on the developer workstation, on a VM or on a container, the server DNS name must always be the same. This article explains how to setup a developer workstation on Fedora, with Libvirt VMs and Podman containers and achieve consistent DNS name resolution. Continue reading
