infra-rebuild
infra-rebuild mirrors nixos-rebuild closely in its command-line interface, but focuses on making infrastructure deployment more convenient. It is built for infrastructure defined in a flake, where each hosts configuration is represented by a different nixosConfiguration
in the flakes output.
For building the configuration of e.g. two hosts called web-01
and git
one can simply run:
infra-rebuild build web-01 git
For deploying the hosts - using the switch operation - it's as simple as:
infra-rebuild switch web-01 git
Here infra-rebuild will simply run nixos-rebuild switch
with the target-host
option set for each host.
Because infra-rebuild tries to be usable without any configuration, by default it queries the hosts FQDN from its nixosConfiguration
and uses that for the target host.
However to override aspects of the target host for specific or all hosts, infra-rebuild also accepts a deployment_configuration.json
as configuration.
Configuration
infra-rebuild accepts optional configuration in a deployment_configuration.json
present in the flake repos root.
The following keys are available to be set for configuring various aspects of deployment for specific or all hosts:
default.targetPort
: A default port to use for connecting to all host.default.targetUser
: A default user to use for connecting to all host.hosts.<host>.targetPort
: The port to use for connecting to<host>
.hosts.<host>.targetUser
: The user to use for connecting to<host>
.hosts.<host>.targetHostname
: The hostname to use for connecting to<host>
.
Example
An example deployment_configuration.json
might look like this then:
{
"default": {
"targetPort": 2222,
"targetUser": "deploy"
},
"hosts": {
"web-01": {
"targetUser": "web-deploy",
"targetHostname": "web-01-intern.infra.example",
"targetPort": 22
}
},
"git": {
"targetUser": "git-deploy"
}
}
Order of Precedence
The order of precedence from least to greatest for targetPort
and targetUser
is the following:
- system default
default.targetPort/User
hosts.<host>.targetPort/User
The order of precedence from least to greatest for targetHostname
is the following:
- FQDN from hosts nixosConfiguration
hosts.<host>.targetHostname
