Mapping from Terraform terms to NixOps:
NIXOPS_STATE (sqlite3 database)Comparison notes:
$ nixops create -d my-unique-deployment-name -s /var/data/nixops/devdeploys.nixops
...
$ nixops deploy -d my-unique-deployment-name -s /var/data/nixops/devdeploys.nixops
...
# make changes to deployment definition now then deploy incremental changes
$ nixops deploy -d my-unique-deployment-name -s /var/data/nixops/devdeploys.nixops
...
# destroy running resources in the deployment my-unique-deployment-name
$ nixops destroy -d my-unique-deployment-name -s /var/data/nixops/devdeploys.nixops
...
# delete deployment definition completely from the database
$ nixops delete -d my-unique-deployment-name -s /var/data/nixops/devdeploys.nixops
...
$ echo $NIXOPS_STATE # points to sqlite3 deployments database to avoid `-s` arg
...
$ nixops list # lists all deployments in $NIXOPS_STATE
...
$ nixops create -d easy-name z/etc/service/default.nix
...
$ nixops deploy -d easy-name
...
$ nixops info -d easy-name # shows state of deployment
...
$ nixops check -d easy-name # runs basic checks on deployment

$ nixops ssh -d easy-name machineName # SSHes into specified machine
...
$ nixops ssh-for-each -d easy-name # Loops SSH through
...
$ nixops list-generations -d easy-name
...
$ nixops show-option -d easy-name machineName services.ntp.servers # shows value of thi

$ nixops backup -d easy-name
