@wangdazhong001 Under different user, the result of 'env' is different.
Regardless of whether it is in the docker container, the same is true in linux
on the host machine. The richer environment variables directly in the container
of worker occur under `roor` user. While the environment variables from the
python task occur under the user whose id is 2.
Since the python script does not execute `source
/opt/dolphinscheduler/conf/env/dolphinscheduler_env.sh`, the python task cannot
read the environment variables in this file.
If you want to access the environment variables from
`/opt/dolphinscheduler/conf/env/dolphinscheduler_env.sh`, there are four
solutions:
1. `open('/opt/dolphinscheduler/conf/env/dolphinscheduler_env.sh', 'r')` and
parse it
2. Use `python-dotenv`
3. Use the following code:
```python
import os
import pprint
import shlex
import subprocess
command = shlex.split("env -i bash -c 'source
/opt/dolphinscheduler/conf/env/dolphinscheduler_env.sh && env'")
proc = subprocess.Popen(command, stdout = subprocess.PIPE)
for line in proc.stdout:
(key, _, value) = line.partition("=")
os.environ[key] = value
proc.communicate()
pprint.pprint(dict(os.environ))
```
4. Use shell task instead of python task
```shell
source /opt/dolphinscheduler/conf/env/dolphinscheduler_env.sh
python /path/to/your_python_script.py
```
