Purpose

provs provides cli-based tooling for provisioning desktop or server resp. perform system checks.

• provs-desktop minimal - provides a minimal setup (e.g. swappiness / randomutils) e.g. for setup on a VirtualBox
• provs-desktop office - provides enhancements like zim / gopass / fakturama
• provs-desktop ide - provides development environments for java / kotlin / python / clojure / terraform
• provs-server k3s - provides a production ready & k3s setup with dualstack option
• provs-syspec - verifies a system according to the provided system spec config file

In general provs combines

• being able to use the power of shell commands
• a clear and detailed result summary of the built-in execution handling (incl. failure handling and reporting)
• the convenience and robustness of a modern programming language

Status

under development - we are working hard on setting up our environments using provs.

Try out

Prerequisites

• A Java Virtual machine (JVM) is required.
• Install jarwrapper (e.g. sudo apt install jarwrapper)
• Download the latest provs-desktop.jar from: https://gitlab.com/domaindrivenarchitecture/provs/-/releases
• Make the jar-file executable by chmod +x provs-desktop.jar
• For server functionality (e.g. k3s) download the latest provs-server.jar from: https://gitlab.com/domaindrivenarchitecture/provs/-/releases

provs-desktop

provs-desktop.jar <type> <target> [<options>]

type can be:

• basic - install some basic packages)
• office - install office software (LibreOffice), E-Mail (Thunderbird), etc
• ide - same as office with additionally ide-software (VSCode, IntelliJ, etc)

target can be:

• local
• user123:mypassword@myhost.com - general format is: <user[:password]@host> -
  • if password is omitted, then ssh-keys will be used for authentication
  • if password is omitted but option -p is provided, then the password will be prompted interactively

options

• -p for interactive password question

Provision a desktop

provs-desktop.jar basic local
# or an office desktop remote:
provs-desktop.jar office myuser@myhost.com -p

In the last case you'll be prompted for the password of the remote user due to option -p.

Provision k3s

provs-server.jar k3s local
# or remote: 
provs-server.jar k3s myuser@myhost.com    # using ssh-authentication - alternatively use option -p for password authentication

For the remote server please configure a config file (default file name: server-config.yaml)

fqdn: "myhostname.com"
node:
  ipv4: "192.168.56.123"   # ip address
echo: true                 # for demo reasons only - deploys an echo app 

To add a grafana agent to your k3s installation add the following to the config:

grafana:
  user: "myusername"   # username for the grafana data source 
  password:
    source: "PLAIN"           # PLAIN, GOPASS or PROMPT
    parameter: "mypassword"   # the password or api key for the grafana data source user 
  cluster: "mycluster"        # a cluster name of your choice  

To provision the grafana agent only to an existing k8s system, ensure that the config (as above) is available and execute:

provs-server.jar k3s myuser@myhost.com -o grafana

Performing a system check

The default config-file for the system check is syspec-config.yaml, you can specify a different file with option -c <config-file>.

provs-syspec.jar local 
# or remote:
provs-syspec.jar myuser@myhost.com

Get help

To get help you can make use of the -h option:

provs-desktop.jar -h
provs-server.jar -h
provs-syspec.jar -h

Or to get help for subcommands e.g.

provs-desktop.jar ide -h
provs-server.jar k3s -h
