Setup CoreDNS w/ etcd backend

Why CoreDNS

[CoreDNS][coredns] was designed from the ground up to provide robust, plugin-based DNS server for use in cloud environments. Namely, it serves as the default primary service discovery mechanism for Kubernetes.

Using CoreDNS allows us to have a lightweight DNS server on RockNSM (11 Mb binary is all that's needed!) to facilitate multi-node service discovery. Alternatively, if another existing DNS service is available, this can be used instead. Aligning with the way the Kubernetes manages service discovery also allows us to build new RockNSM features in parallel with the coming Kubernetes support.

RockNSM Application

dcode

Podman has recently added support for named volumes, which is super handy. As of today (2018-01-17), it supports the local driver, which effectively will bind-mount a tracked directory into one or more containers. It's helpful to be able to limit the size of data volumes though so that one container doesn't exhaust the resources of another.

Fortunately, the XFS filesystem let's us handle this natively using "project quotas". XFS allows setting quotas based on username, group, or project. The project quota effectively maps a project ID to a path on a filesystem.

unzip $(basename ${CERT_URL})

# Creates new pod named `test` with `running` status with `infra` container only
sudo podman pod create --name test

# Pauses the named pod and all containers in the pod
sudo podman pod pause test

# Unpauses the named pod and all containers in the pod
sudo podman pod unpause test

First, you need to enable the vhost config in lighttpd:

sudo sed -i '/^#.*vhosts\.d\/\*\.conf/ s/^#//' /etc/lighttpd/lighttpd.conf

Finally create the lighttpd docket vhost log dir

sudo mkdir -p /var/log/lighttpd/docket

dcode

# Dockerfile for lighttpd

FROM centos/systemd

RUN yum install -y epel-release; \
        yum update -y; \
        yum install -y lighttpd; \
        yum clean all; \
        rm -rf /var/cache/yum/*; \
        systemctl enable lighttpd;
