QUESTION
I'm hosting an ASP.NET Core Docker web app in the open source Caprover Paas in a Linux VM and it runs fine. Using the Caprover interface, I was able to configure the site's LetsEncrypt SSL certificate and the browser shows a padlock and says connection is secure. The problem is that ASP.NET doesn't detect the app is running in Https mode and Request.IsHttps
is always false. Here's my test.

...ANSWER
Answered 2022-Feb-22 at 02:17As suspected, the issue is Nginx proxy server handles the encryption/decryption of https connections but when forwarding the request to the container, it uses plain http. So asp.net never sees the https connection since it's terminated at the proxy server. The solution is to forward X-Forwarded-For
and X-Forwarded-Proto
headers. See below modifications.

QUESTION
I'm trying to connect a Json file which resides in a docker volume of the following container to my main docker container which is running a django project.
Since I am using Caprover my Docker Compose options are very limited. So Docker Composer is not really an option. I want to instead just expose the json file over the web with a link.
Something like domain.com/folder/jsonfile.json
Can somebody tell me if this is possible inside this dockerfile?
The image I am using is crucial to the container so can I just add an nginx
image or do I need any other changes to make this work?
Or is nginx
not even necessary?
ANSWER
Answered 2022-Jan-17 at 17:47If you want to just have two containers access the same file, just use a volume with --mount.
QUESTION
I'm using Caprover with Docker to run a Django project (Django-Cookiecutter) which is non persistent. I'm also running a persistent app on the same server which imports csv data. I need the two apps to basically share a file together. This is how i imagined it:
- The importer app imports csv data and stores it as a json file inside a specific folder.
- The Django app accesses the json file in that folder and uses a script i wrote to import the json into the database. I'm struggling to understand how i can access the folder inside my importer app containing the json file from my django app. Does anyone have an idea on how i can make this happen between those two docker containers?
ANSWER
Answered 2022-Jan-11 at 21:46You can share a directory or file between the two containers by mounting the same directory in both containers. Here's a simple docker-compose example where two containers mount the same directory. Then the first container writes to a file and the second container reads from it.

I'm using caprover which uses docker to deploy postgresql 12. Right now my postgresql database is constantly restarting and printing this log everytime:
...ANSWER
Answered 2021-Mar-09 at 03:38That means that you lost WAL information, that is, you lost a file or file contents from at least one of the files in the pg_wal
subdirectory of the PostgreSQL data directory.
If PostgreSQL crashed, it will recover using the transaction log (WAL). This recovery starts from a checkpoint, whose location is found in the control file (global/pg_control
). The error message indicates that at the indicated position in the WAL, no checkpoint is found, so PostgreSQL cannot recover.
You have lost some data that is vital to the database. Perhaps a file got deleted, perhaps you have unreliable storage that loses data that an fsync
request confirmed to be on disk.
Restore from a backup or hire a PostgreSQL expert to salvage data from the remains of your database.
QUESTION
Hopefully this is a newbie Caprover question. I have created a new app under "Apps" and I am trying to deploy my .Net Core application to it.
When I try to run the caprover deploy command, I can select the new "app" that I have created.
How can I change the application to point to https://www.instatranscribe.com
(instead of https://app.instatranscribe.com
) i.e deploy the application to the root domain instead of the subdomain?
ANSWER
Answered 2020-Nov-07 at 17:08Thank you @poke for your input. I was able to fix the issue by changing the app name from app
to www
