Creating a Python virtual environment resource

After you have created the requirements.txt file, you can create the Python virtual environment resource.

CDE CLI
Web UI

Before you begin

Download and configure the CDE CLI.
Create a requirements.txt file specifying the Python package and version dependencies required by your CDE job.

Steps

Run the cde resource create command as follows to create a Python virtual environment resource.
note
You can also specify a PyPi mirror for a Python virtual environment resource using the --pypi-mirror flag. This requires network access to the mirror from the CDP environment.
```
cde resource create --name cde-python-env-resource --type python-env --python-version python3
```
Upload the requirements.txt file to the resource.
note
For python-env resources, you can only upload a requirements.txt file. Python environment resources do not support arbitrary file upload. If the local file is named something other than requirements.txt, you must add the flag --resource-path requirements.txt to the command, which renames the file to requirements.txt in the resource.
```
cde resource upload --name cde-python-env-resource --local-path ${HOME}/requirements.txt
```

Result

When you first create a Python virtual environment resource, CDE builds the environment according to the requirements.txt file. During this build time, you cannot run a job associated with the virtual environment. You can check the status of the environment by running cde resource list-events --name <resource_name>. For example:

cde resource list-events --name cde-python-env-resource

The environment is ready when you see a message similar to the following:

  {
    "id": 4,
    "message": "Job pp-84kgdgf6-resource-builder-cde-python-env-resource-1634911572 succeeded, marking resource with ready status",
    "created": "2021-10-22T14:09:13Z"
  }
