See no web ui when following quickstart guide

[zhangcheng]

Trying to follow the quickstart guide to the step of astro dev start.

I can’t see the web UI on port 8080 properly.

Have no idea how to further debug this problem. ;-(
Would appreciate any help to unblock the current situation. Thanks in advance.

My trace:

My setup is MacOS 12.0.1 with Docker Desktop 4.3.1.

Tried troubleshooting suggestions of earlier similar posts regarding Docker engine, but still not working.

My Docker resources settings allocate 9GB memory by default, all 3 airflow related containers run stable, no the issue of container keep restarting.

Also tried “Clean / Purge data” of docker engine, and no use.

Try running docker logs <container id> on the webserver and scheduler container to get more information on why the webserver is not healthy.

Verified via psql that I can login to the postgresql container at localhost:5432.

Any option that I can bump up the logging level of the webserver and scheduler container?

I have the exact same problem with Mac 12.0 and Docker 4.3.2.
Did you managed to workaround it?

[rbankston]

Could you try upgrading your astro cli to 0.27.1, deleting your ~/.astro/config.yaml and then doing astro dev stop && astro dev start from your project folder?

[zhangcheng]

Upgraded astro cli to 0.27.1, deleted ~/.astro/config.yaml, did astro dev stop && astro dev start, still same problem as above.
The newly created config.yaml is identical to the one created by 0.27.0.
@rbankston

[zhangcheng]

Not yet, no clue either.

[zhangcheng]

I think I found out why.
The address for Postgres container of 0.0.0.0:5432 is not accessible by both webserver and scheduler container.

astro@66e5853cd8bf:/usr/local/airflow$ nc -v 0.0.0.0 5432
nc: connect to 0.0.0.0 port 5432 (tcp) failed: Connection refused
astro@66e5853cd8bf:/usr/local/airflow$ nc -v 192.168.3.141 5432
Connection to 192.168.3.141 5432 port [tcp/postgresql] succeeded!

where 192.168.3.141 is the ip of my mac.

so after I change the config.yaml as above, I can now open the web UI.

I faced the same problem on the same version of astro CLI (0.27.0) on Mac OS and upgrade to 0.27.1 helped me. The address for postgres container in config.yaml was changed from “0.0.0.0” to “postgres”:

In my case, i tried to change the ports of PostgreSQL and webserver, but it did not work, but what it worked for me was to disable the

• Use Docker Compose V2 release candidate
• Use the new Virtualization framework

options in the “Experimental features” section of Mac Os Docker Desktop.
