This is a terraform module to create a spot instance running Selenoid in AWS. For now only spot instances are supported and it was the main use cases I needed. Support for "on demand" instances will be added shortly
The instance is created using the RancherOS AMI. The reasoning for this is that I was looking for a container OS given that selenoid is ran using docker within the image. RancherOS was the easiestt to configure using cloud-init, given that CoreOS was moved to Ignition based setup in the latest versions.
Once the operating system starts selenoid is setup using Aerokube CM tool.
Saving videos to S3 currently requires you to build Selenoid yourself using a custom build tag, as described in the Selenoid documentation. For the moment this is not supported by this module but support is likely to come soon.
The most recent version of the browsers you specify in the browsers parameter of the module will be used.
To find out more about the format of the browser argument refer to Aerokube CM documentation https://aerokube.com/cm/latest/#_downloading_only_some_browser_versions. Some other examples are:
firefox:51.0;firefox:55.0;chrome:66.0
firefox:>51.0,<=55.0;opera

"firefox;chrome" |
no |
| cpu_count | The number of CPU's of the instance. This will be passed to Selenoid as --limit CLI parameter. This tell Selenoid how many concurrent containers it can run. You should assign a value according to the number of CPU's of the instance type. | number |
