We waited for 60 seconds previously which is exactly when the
supplied ssh key would disappear in my setup. So instead we
wait for slightly shorter (55 seconds) to ease this for me.
For a reason, current wget versions error out when using localhost instead
of 127.0.0.1 as the healthcheck for docker services. Probably has something
to do with dns resolution - either on docker or wget end, but have not
looked to deep into it.
When launching many containers gitea admin waiting still sometimes gets stuck.
This should provide a bandaid for now. Also improve the container detection.
Admin deployment was very timing-dependent: If the server took a while
to set it up, it would always error out while deploying. This commit
adds sufficient grace-time into the admin request call before the error
occurs which should avoid it in most deployments (unless the server is
severely underpowered or over-taxed).
Also fixes admin creation to avoid root usage in the container when it
is not called for.
