[wehappyfew]

At Holograph we need to use Safe on k8s, so here it is an initial version of the Helm chart :]

Note:
I'm still facing issues, so any pointers would be greatly appreciated :]

@wehappyfew Thank you very much for your contribution! Could you let us know what issues are you facing?

@luarx @diegopazosrego Could you take care of reviewing this PR?

Hey @Uxio0 ! Happy to contribute :]
So, the issues I'm facing are the following:
[keep in mind that I'm not a blockchain dev, and I'm still figuring out the inner works of Safe architecture :) ]

1. I had trouble using Safe UI [safe-wallet-web] as is, cause I needed it to listen on 0.0.0.0:3000 in order to be used with an ingress in k8s.

2. When I access the Safe UI in my browser [Brave] I get this error in the console [even when I have set the NEXT_PUBLIC_WC_PROJECT_ID var]

3. Also, I cannot access http://localhost:8000/cfg/media and http://localhost:8000/cgw/v1/chains

4. I dont know If 2 is responsible, but no 'Connect wallet' button is responsive, and no error is thrown and the console [or in the pod] to give me pointers :/

5. Note: most of the config vars across the infra have sample values

6. Also, could you please validate if the way the nginx-shared-txs volume is correctly shared between the nginx and tcs-web deployments?

All in all, I tried to translate your docker-compose file by studying the safe-infrastructure repo. Please give me any pointers if anything is off :]

Thanks again!

Also, when I try to access the Django admin dashboard for the transaction service, [after I run python manage.py createsuperuser] , I get the page with broken css...

eg http://localhost:58697/admin/history/
