QUESTION
Summary:
I want to make NGINX (not NGINX Plus) re-resolve the IP address from the DNS name by using a variable in proxy_pass
(as suggested in this official Nginx article in the section "Setting the Domain Name in a Variable"). But when I do that it won't set/forward the correct Content-Type
header, but always use text/html
, for .css
, .js
etc. files.
My setup:
I have a frontend and a backend service running in separate Docker containers (to be deployed to OpenShift in production). There's also a third container that runs nginx:latest
(v1.19.9 as of today) and acts as a reverse proxy, forwarding calls made to /my-app
to the frontend and /my-app/api
to the backend container. The NGINX reverse proxy has set them up as upstream servers using their DNS names.
All three containers run within the same custom Docker network, so resolving in itself works fine - but only, when NGINX is (re-)started.
The problem:
When the frontend or backend container gets restarted it may get a new IP address. Since NGINX caches IP addresses I'm getting a 502
when I make calls to them. I want NGINX to re-resolve the IP address more frequently, like NGINX Plus does. This is how the problem with the Content-Type
came up, when I tried to have NGINX re-resolve DNS names.
The configuration:
Here's my NGINX configuration (simplified to the relevant stuff only):
ANSWER
Answered 2021-May-24 at 16:12This isn't a problem with Content-Type
. You are using proxy_pass
incorrectly. As you have already noted:
When using variables in proxy_pass, if URI is specified, it is passed to the server as is, replacing the original request URI.
You currently have the following working configuration, but you want to replace it with a variable to force DNS resolution:

QUESTION
We have been trying git flow in our team. We create release branch base off of develop
branch. Then we merge release branch to develop
and master
after release. We have made several releases so far without hotfix.
Now, we just had an incident that needed a hotfix (first hotfix). so we created hotfix branch based off of master
. We merged hotfix branch to master, it was all good. Then we tried to merge hotfix branch to develop
, and diff shows old changes being reintroduced to develop
. For example, there are files that should have been deleted but were re-added into develop after merge. Prior to merging, both staging and master are the same (no diff whatsoever).
Any idea what is causing this? I wanted to show sample history/graph but our history is very cluttered due to merges.
...ANSWER
Answered 2021-May-04 at 21:27Any idea what is causing this?
The choice of merge base commit, of course. This choice is not yours: Git makes it automatically, based on the commit graph. That's why this step:
so we created hotfix branch based off of
master
was probably the founding error (or "root cause", if you prefer).
You can see which commits Git considers to be the merge base(s) for develop
and master
using:
QUESTION
I am working on a huge repository and we are total 900 people who are working on the same, creating a new branch for each feature/bug/hotfix (lets call it "custom branch") we are working on and deleting the same after successful testing and merging it into the mainline branch(Total: 5), which leads us to the errors like unable to lock local ref
.
Our repository structure is in following format for staging:
...ANSWER
Answered 2021-Apr-23 at 00:33Is it recommended? I don't know: it seems like this would depend on who is doing the recommendations.
Will it create further issues? No, but it won't solve them either.
Is it possible to have such a configuration? Yes, of course, you demonstrated that yourself.
Can you configure
git clone
to do this? Not precisely, no:git clone --single-branch
gets close though, and after doing that, you can usegit remote set-branches --add
to add the four remaining branches, so that instead of a single-branch clone, you have a five-branch clone.
Your best bet, though, would be to figure out why your systems are doing this. That's usually a sign of running multiple parallel git fetch
operations on a single repository (don't do that!).
It sounds like you have multiple users sharing a single Git repository in which they try to do work. Don't do that! Git repositories are meant to be private to each developer.
QUESTION
I'm trying to build my nx application in github actions with nx cloud enabled. I always get the fatal: No such ref: 'main~1'
error.
The command nx affected --target=build --base=main~1 --head=HEAD --parallel --with-deps
works before I commit, but after I commit, the command no longer works locally or in ci.
Based on the docs, setting the base to main~1
should just compare it to the previous commit of the main branch.
Full error in Github Actions:
...ANSWER
Answered 2021-Apr-21 at 18:31Okay... so I finally figured out what's going on. After logging git show-ref
in github actions, I found that the actions/checkout
action by default only checks out one commit.
Only a single commit is fetched by default, for the ref/SHA that triggered the workflow.
After specifying the fetch-depth: 0
to fetch all the refs for all the branches, it worked. Nx is able to properly compare the difference between the different branches and previous commits in the same branch.

Answered 2021-Apr-19 at 09:01As a rule of thumb never render anything from Django directly inside javascript. This can lead to potential XSS attacks. If you want data from the server either use AJAX if it is needed dynamically or you can use the json_script
template filter [Django docs] if it is needed only once when the page gets loaded:

Generally speaking, it is set in the "Project Structure" dialog.
Go to File > Project Structure > SDK Location. The third field is "JDK Location" where you can set it. This will set it for the current project.

I have the below piece of script that I am having issues with. It is supposed to use variables assigned outside of a job ($FilePath and $Computer) to gather the hot fixes installed on the specified machine and save that information on the system the script is running on.
In this senario, $host_array only contains 127.0.0.1; so $Computer = 127.0.0.1. The loopback address works with the commands, so aside from the error I am getting (listed below the script); I am not sure what I am doing wrong.
