@daniel i guess this can be solved by the information you provided in another thread:
Copy code
Or if you want to be able to use a run launcher to execute your pipeline in a different process like dagit does, we have an option for that as well, it's just a little bit more hidden currentlyhidden optiond

11/13/2020, 8:27 PMcan you store the credentials in environment variables?
if so, you can configure the yaml to read those environment variables

11/13/2020, 8:29 PM@sashank that is a good idea, i think i should be able to do that

11/13/2020, 8:30 PMif so, you can usually use
env: ENV_VAR_NAMEfor example:
instead of:
Copy code
event_log_storage:
module: dagster_postgres.event_log
class: PostgresEventLogStorage
config:
postgres_db:
username: my_username
password: my_password
hostname: my_host
db_name: my_db
port: 5432you can do:
Copy code
event_log_storage:
module: dagster_postgres.event_log
class: PostgresEventLogStorage
config:
postgres_db:
username:
env: DAGSTER_PG_USERNAME
password:
env: DAGSTER_PG_PASSWORD
hostname:
env: DAGSTER_PG_HOST
db_name:
env: DAGSTER_PG_DB
port: 5432and we’ll automatically load those values from the environment variable instead
