step.environment
ΒΆ
Environment defines the hardware and the location where to run your code.
Environments encapsulate the following information:
- Who owns the environment instances?
- Are you running on Azure, Amazon, Google, OpenStack or on-premises?
- Are you running in USA, Asia, Europe, etc.
- How much memory and CPU is available?
- Does it have GPUs?
Environment defined in the YAML is the default value for executions of that particular step type. In other words, it can overwritten by selecting a separate environment in the web interface dropdown or with vh exec run -e <SLUG> <STEP_NAME>
command-line parameter.
You can use vh environments
command to see available environments after logging in.
The most common environment slug syntax is <OWNER_IF_NOT_VALOHAI>-<CLOUD_PROVIDER>-<LOCATION>-<HARDWARE_TYPE>
. For example:
environment: aws-eu-west-1-g3s-xlarge
environment: acme-azure-westeurope-nc24
environment: awesome-corporation-gcp-europe-west4-b-custom-2-8192
Tip
It is wise to use an environment in the same data center or geographical location as your data store to minimize the data transfer durations.
