This adds Dependabot to keep things updated and Coveralls so we can see how code coverage changes over time. Coveralls / SimpleCov are configured so that both the SimpleCov html report and the Coveralls report are generated. This facilitates easily seeing coverage locally in addtion to via CI.

### Example workflow
|
|
|
|
Grabbing a token for authenticated pooler requests:
|
|
|
|
```bash
|
|
floaty token get --user username --url https://vmpooler.example.net/api/v1
|
|
```
|
|
|
|
This command will then ask you to log in. If successful, it will return a token that you can save either in a dotfile or use with other cli commands.
|
|
|
|
Grabbing vms:
|
|
|
|
```bash
|
|
floaty get centos-7-x86_64=2 debian-7-x86_64 windows-10=3 --token mytokenstring --url https://vmpooler.example.net/api/v1
|
|
```
|
|
|
|
### vmfloaty dotfile
|
|
|
|
If you do not wish to continually specify various config options with the cli, you can have a dotfile in your home directory for some defaults. For example:
|
|
|
|
#### Basic configuration
|
|
|
|
```yaml
|
|
# file at ~/.vmfloaty.yml
|
|
url: 'https://vmpooler.example.net/api/v1'
|
|
user: 'brian'
|
|
token: 'tokenstring'
|
|
```
|
|
|
|
Now vmfloaty will use those config files if no flag was specified.
|
|
|
|
#### Default to Puppet's ABS instead of vmpooler
|
|
|
|
```yaml
|
|
# file at ~/.vmfloaty.yml
|
|
url: 'https://abs.example.net'
|
|
user: 'brian'
|
|
token: 'tokenstring'
|
|
type: 'abs'
|
|
```
|
|
|
|
#### Configuring multiple services
|
|
|
|
Most commands allow you to specify a `--service <servicename>` option to allow the use of multiple vmpooler instances. This can be useful when you'd rather not specify a `--url` or `--token` by hand for alternate services.
|
|
|
|
To configure multiple services, you can set up your `~/.vmfloaty.yml` config file like this:
|
|
|
|
```yaml
|
|
# file at /Users/me/.vmfloaty.yml
|
|
user: 'brian'
|
|
services:
|
|
main:
|
|
url: 'https://vmpooler.example.net/api/v1'
|
|
token: 'tokenstring'
|
|
alternate:
|
|
url: 'https://vmpooler.example.com/api/v1'
|
|
token: 'alternate-tokenstring'
|
|
```
|
|
|
|
- If you run `floaty` without a `--service <name>` option, vmfloaty will use the first configured service by default.
|
|
With the config file above, the default would be to use the 'main' vmpooler instance.
|
|
- If keys are missing for a configured service, vmfloaty will attempt to fall back to the top-level values.
|
|
With the config file above, 'brian' will be used as the username for both configured services, since neither specifies a username.
|
|
|
|
Examples using the above configuration:
|
|
|
|
List available vm types from our main vmpooler instance:
|
|
|
|
```bash
|
|
floaty list --service main
|
|
# or, since the first configured service is used by default:
|
|
floaty list
|
|
```
|
|
|
|
List available vm types from our alternate vmpooler instance:
|
|
|
|
```bash
|
|
floaty list --service alternate
|
|
```
|
|
|
|
#### Using a Nonstandard Pooler service
|
|
|
|
vmfloaty is capable of working with Puppet's [nonstandard pooler](https://github.com/puppetlabs/nspooler) in addition to the default vmpooler API. To add a nonstandard pooler service, specify an API `type` value in your service configuration, like this:
|
|
|
|
```yaml
|
|
# file at /Users/me/.vmfloaty.yml
|
|
user: 'brian'
|
|
services:
|
|
vm:
|
|
url: 'https://vmpooler.example.net/api/v1'
|
|
token: 'tokenstring'
|
|
ns:
|
|
url: 'https://nspooler.example.net/api/v1'
|
|
token: 'nspooler-tokenstring'
|
|
type: 'nonstandard' # <-- 'type' is necessary for any non-vmpooler service
|
|
abs:
|
|
url: 'https://abs.example.net/'
|
|
token: 'abs-tokenstring'
|
|
type: 'abs' # <-- 'type' is necessary for any non-vmpooler service
|
|
|
|
```
|
|
|
|
With this configuration, you could list available OS types from nspooler like this:
|
|
|
|
```bash
|
|
floaty list --service ns
|
|
```
|
|
|
|
#### Valid config keys
|
|
|
|
Here are the keys that vmfloaty currently supports:
|
|
|
|
- verbose (Boolean)
|
|
- token (String)
|
|
- user (String)
|
|
- url (String)
|
|
- services (String)
|
|
- type (String)
|
|
|
|
### Tab Completion
|
|
|
|
There is a basic completion script for Bash (and possibly other shells) included with the gem in the [extras/completions](https://github.com/puppetlabs/vmfloaty/blob/master/extras/completions) folder. To activate, that file simply needs to be sourced somehow in your shell profile.
|
|
|
|
For convenience, the path to the completion script for the currently active version of the gem can be found with the `floaty completion` subcommand. This makes it easy to add the completion script to your profile like so:
|
|
|
|
```bash
|
|
source $(floaty completion --shell bash)
|
|
```
|
|
|
|
If you are running on macOS and use Homebrew's `bash-completion` formula, you can symlink the script to `/usr/local/etc/bash_completion.d/floaty` and it will be sourced automatically:
|
|
|
|
```bash
|
|
ln -s $(floaty completion --shell bash) /usr/local/etc/bash_completion.d/floaty
|
|
```
|
|
|
|
## vmpooler API
|
|
|
|
This cli tool uses the [vmpooler API](https://github.com/puppetlabs/vmpooler/blob/master/API.md).
|
|
|
|
## Using the Pooler class
|
|
|
|
vmfloaty providers a `Pooler` class that gives users the ability to make requests to vmpooler without having to write their own requests. It also provides an `Auth` class for managing vmpooler tokens within your application.
|
|
|
|
