Where is the progress update?

[khaledyoussef24]

deployed a machine and was working locally implemented the same logic was at taiga image
and made finally this docker image
https://hub.grid.tf/khaledyoussef1.3bot/khaledgx96-gitea-latest.flist
but it had a problem with the environment variables.

but got some remarks from petter and some improvements as well.

it is better to build the docker image for service from the binary not create a docker image inside the docker image

working on those changes.

Work done

• Changed from docker compose to bash script.
• after the docker image builds the machine gets stuck and can not connect to it.
• the zinit always giving that the gitea is successfully built
• added nginx so it can be accessed by https.
• added ufw to close the unnecessary ports in the machine allowing only port 22 for ssh and port 3000 for the solution.
• still working on some improvements.
• also removed postgres and used sql:lite

work to be added

• make sure that the image stable and usable always
• fix the port issue to be working on port 80 to be usable if added to the grid
• adding caddy to the docker image
