Config Files: autosign.conf
Included in Puppet Enterprise 3.3. A newer version is available; see the version menu above for details.
The autosign.conf
file can allow certain certificate requests to be automatically signed. It is only valid on the CA puppet master server; a puppet master that is not serving as a CA will not consult autosign.conf
.
More About Autosigning
Puppet also provides a policy-based interface for autosigning, which can be more flexible and secure. The autosign.conf
file is the simpler and less secure method.
For more details, see the reference page about certificate autosigning.
Location
The autosign.conf
file is located at $confdir/autosign.conf
by default. Its location is configurable with the autosign
setting.
The location of the confdir
varies; it depends on the OS, Puppet distribution, and user account. See the confdir documentation for details.
Format
The autosign.conf
file is a list of certnames or domain name globs (one per line). Each line represents a node name or group of node names whose certificate requests should be automatically signed when the CA puppet master receives them.
rebuilt.example.com
*.scratch.example.com
*.local
Note that domain name globs do not function as normal globs: an asterisk can only represent one or more subdomains at the front of a certname that resembles a fully-qualified domain name. (That is, if your certnames don’t look like FQDNs, you can’t use autosign.conf
to full effect.
Note: Since any host can request any certname, autosigning with autosign.conf
is essentially insecure. See the reference page about certificate autosigning for more context.
