Loader just spins upon launch

[IAmStoxe]

After following the very easy steps of cloning and make up I am left with the below spinner (forever) when launching :3001

Hi there! Do you still have this issue?

What's your operation system? What is the output in the console?

I'm having a very similar issue. Here are the OSes I've tried (all are 64-bit): (1) Debian 10 on Hyper-V (Win Server 2019) -> Horrible memory leakage (unrelated to Plynx; seems to be WSL + docker issue) that fills up to 64GB of RAM before crashing (2) Ubuntu 20 LTS on Hyper-V (Win Server 2019), CentOS 8 on Hyper-V (Win Server 2019), Debian 10 on VMWare Fusion (Mac OS), Debian 10 on VMWare ESXi -> "make build," "make up" results in dashboard loading with a forever spinner (and none of the middle menu items work; only the top menu links to GitHub, plynx.com, etc. work); after that, any redirect ends up being a blank screen: e.g., http://10.11.204.34:3001/templates/basic-dag-workflow

I have also tried (on all the above VMs) launching the individual UI + Plynx api/workers on their own (no containers; each launched using a separate Linux process) with a standalone MongoDB instance and everything seems to connect fine and "work" (no terminal error messages), but the same behavior (blank pages). I even hard-coded paths in ui/src/configConsts.js, config.yaml, and docker-compose.yml, but it made no difference.

RESOLVED

The issue seems related to docker container routing outside of MacOS environment (which presumably is what the project developers have been using exclusively for dev/testing of the plynx ecosystem). On Windows Server 2019 + docker, or any modern Debian/RHEL flavor of *nix, the following works:

(1) Modify plynx/ui/src/configConsts.js to return the hard-coded server path (e.g., https://www.mysite.com/plynx/api/v0) (2) Modify the docker compose and config files to NOT build/launch the UI or nginx containers (3) Build the UI/react elements individually (cd ui; npm run build) (4) Install Nginx on the host, create a plynx_ui.conf as appropriate, and create a symbolic link from Nginx root folder (e.g., /var/www/html) to the plynx/ui/build folder; essentially, Nginx will be serving as the r-proxy, load balancer, and HTTP server (5) Launch the other services (flask+DB) via provided docker compose config (e.g., $ sudo make build; sudo make up) (*) Use systemd service script to daemonize the above

Thanks Ashton! The issue looks very weird. Not sure yet how to fix it given that I don't have Windows machine.

I hoped docker + docker-compose would make running plynx easier, so that you don't have to rebuild everything from scratch

[amozano]

Agreed, docker was supposed to make life easier, lol!

Have you experienced any issues launching on Debian 10 or Ubuntu 20.04 or CentOS 8? I've experienced an identical issue on all 3.

I'm having the same issue on Ubuntu 20.04.
