v0.6.1

Updates

CoreDHCP/CoreSMD

Add netmask/cidr action to set DHCP option 1 (network mask) per-rule. (Also add more unit tests, fixes, and docs updates.)

Rule documentation is now at examples/coredhcp/rules.md.

v0.6.0

Updates

CoreDHCP/CoreSMD

New Rich Rules

Specify DHCP settings to set for specific nodes based on matching specifiers using rule= setting. Logging levels can be specified with rule_log=. See examples/coredhcp/hostnames.md for more details as well as examples/coredhcp/coredhcp*.yaml for examples.

node_pattern and bmc_pattern are deprecated, and are automatically converted to rules if specified in the config file. See here for steps on how to migrate.

Full Changelog: v0.4.0...v0.4.1

v0.4.0

Updates

Container Name Change

Instead of the container's path being ghcr.io/openchami/coredhcp, it is now ghcr.io/openchami/coresmd. Pull this version via:

podman pull ghcr.io/openchami/coresmd:v0.4.0

This name change is because CoreSMD now supports CoreDNS in addition to CoreDHCP and uses the same image for both.

New CoreDNS Plugin

CoreDNS functionality is now here!

This can be hooked into an existing OpenCHAMI installation. For instance, use the following quadlet:

[Unit]
Description=The coredns container
Wants=haproxy.service
After=haproxy.service
PartOf=openchami.target

[Container]
ContainerName=coredns

HostName=coresmd
Image=ghcr.io/openchami/coresmd:v0.4.0

Exec=/coredns

#Capabilities
AddCapability=NET_ADMIN
AddCapability=NET_RAW

# Volumes
Volume=/etc/pki/ca-trust/extracted/pem/tls-ca-bundle.pem:/root_ca/root_ca.crt:ro,Z
Volume=/opt/shared/coresmd/Corefile:/Corefile

# Networks for the Container to use
Network=host

# Unsupported by generator options
# Proxy settings
PodmanArgs=--http-proxy=false

[Service]
Restart=always

Example Corefile (/opt/shared/coresmd/Corefile in quadlet above):

# Basic CoreSMD CoreDNS Configuration
# This configuration provides DNS resolution for OpenCHAMI cluster components

.:53 {
    ready
    bind 172.16.0.254
    coresmd {
        smd_url https://demo.openchami.cluster:8443
        ca_cert /root_ca/root_ca.crt
        cache_duration 30s
        zone openchami.cluster {
            nodes de{03d}
        }
    }
    prometheus 0.0.0.0:9153
    forward . 8.8.8.8
}

With the above:

• Resolve nodes using NID:

  $ dig @172.16.0.254 re002.openchami.cluster
  de002.openchami.cluster.     60      IN      A       172.16.0.2
  

• Resolve nodes via xname:

  $ dig @172.16.0.254 x3000c0s0b1n0.openchami.cluster
  x3000c0s0b1n0.openchami.cluster. 60  IN      A       172.16.0.2
  

• Reverse lookup a node's IP:

  $ dig @172.16.0.254 -x 172.16.0.2
  2.0.16.172.in-addr.arpa. 60     IN      PTR     x3000c0s0b1n0.openchami.cluster.
  

• Resolve BMCs via xname:

  $ dig @172.16.0.254 x3000c0s0b1.openchami.cluster
  x3000c0s0b1.openchami.cluster. 60    IN      A       172.16.0.102
  

• Reverse lookup a BMC's IP:

  $ dig @172.16.0.254 -x 172.16.0.102
  102.0.16.172.in-addr.arpa. 60   IN      PTR     x3000c0s0b1.openchami.cluster.
