|
|
|
|
## Purpose
|
|
|
|
provs provides cli-based tools for
|
|
* provisioning a desktop (various kinds)
|
|
* provisioning a k3s server
|
|
* performing system checks
|
|
|
|
Tasks can be run locally or remotely.
|
|
|
|
## Status
|
|
|
|
under development - though we already set up a few IDEs and servers with provs.
|
|
|
|
## Try out
|
|
### Prerequisites
|
|
|
|
* A **Java Virtual machine** (JVM) is required.
|
|
* Install `jarwrapper` (e.g. `sudo apt install jarwrapper`)
|
|
* Then either download the binaries or build them yourself
|
|
|
|
#### Download the binaries
|
|
|
|
* Download the latest `provs-desktop.jar`,`provs-server.jar` and/or `provs-syspec.jar` from: https://gitlab.com/domaindrivenarchitecture/provs/-/releases
|
|
* Preferably into `/usr/local/bin` or any other folder where executables can be found by the system
|
|
* Make the jar-file executable e.g. by `chmod +x provs-desktop.jar`
|
|
|
|
#### Build the binaries
|
|
|
|
Instead of downloading the binaries you can build them yourself
|
|
|
|
* Clone this repository
|
|
* In the repository's root folder execute: `./gradlew install`. This will install the binaries in `/usr/local/bin`
|
|
|
|
### Provision a desktop
|
|
|
|
After having installed `provs-desktop.jar` (see prerequisites) execute:
|
|
|
|
`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`
|
|
* remote, e.g. `user123:mypassword@myhost.com` - general format is: <user[:password]@host> -
|
|
* be sure to have openssh-server installed
|
|
* add your preferred public key to known_hosts on the target machine
|
|
* 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
|
|
* `-o` for only executing one action, e.g.
|
|
* `-o verify` for verifying your installation
|
|
* `-o firefox` to install firefox from apt on ubuntu
|
|
* `-o teams` to install MS-Teams
|
|
|
|
|
|
#### Example
|
|
|
|
```bash
|
|
provs-desktop.jar basic local # installs a basic desktop on a local machine
|
|
provs-desktop.jar office myuser@myhost.com -p # installs an office desktop on a remote machine, prompting for password
|
|
provs-desktop.jar ide myuser@myhost.com # installs an ide on a local machine
|
|
provs-desktop.jar ide myuser@myhost.com -o firefox # installs firefox on a remote machine
|
|
provs-desktop.jar ide myuser@myhost.com -o verify # verifies the installation on a remote machine
|
|
```
|
|
|
|
### Provision a k3s Server
|
|
|
|
```bash
|
|
provs-server.jar k3s local # installs a k3s server locally
|
|
provs-server.jar k3s myuser@myhost.com # install remote k3s using ssh-authentication // option -p for password authentication
|
|
provs-server.jar k3s myuser@myhost.com -c path/to/k3sServerConfig.yaml -a path/to/application.yaml # as above, but define paths to your application and config yamls
|
|
```
|
|
|
|
For the remote server please configure a config file (default file name: server-config.yaml).
|
|
It has to be in the same folder where you execute the provs-server.jar command.
|
|
```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:
|
|
|
|
```yaml
|
|
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:
|
|
|
|
```bash
|
|
provs-server.jar k3s myuser@myhost.com -o grafana
|
|
```
|
|
|
|
Reprovisioning the server can easily be done using the -r or --reprovision option.
|
|
|
|
```bash
|
|
provs-server.jar k3s myuser@myhost.com -c path/to/k3sServerConfig.yaml -a path/to/application.yaml -r #
|
|
```
|
|
|
|
Or you can add `reprovision: true` to your k3sServerConfig.yaml.
|
|
|
|
### Perform 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>`.
|
|
|
|
```bash
|
|
provs-syspec.jar local
|
|
# or remote with a custom config filename
|
|
provs-syspec.jar myuser@myhost.com -c my-syspec-config.yaml
|
|
```
|
|
|
|
Example output:
|
|
|
|
|
|
|
|
## Get help
|
|
|
|
To get help you can make use of the `-h` option:
|
|
|
|
```bash
|
|
provs-desktop.jar -h
|
|
provs-server.jar -h
|
|
provs-syspec.jar -h
|
|
```
|
|
|
|
Or to get help for subcommands e.g.
|
|
|
|
```bash
|
|
provs-desktop.jar ide -h
|
|
provs-server.jar k3s -h
|
|
```
|
