I'd like to use envsubst with nginx docker alpine. Documentation:

Using environment variables in nginx configuration (new in 1.19)

Out-of-the-box, nginx doesn't support environment variables inside most configuration blocks. But this image has a function, which will extract environment variables before nginx starts.

Here is an example using docker-compose.yml:

web: image: nginx volumes:

• ./templates:/etc/nginx/templates ports:
• "8080:80" environment:
• NGINX_HOST=foobar.com
• NGINX_PORT=80

By default, this function reads template files in /etc/nginx/templates/*.template and outputs the result of executing envsubst to /etc/nginx/conf.d.

I have a nginx container service of the form:

I need to create a method that reads a html file then display the number of word occurrence.

for example: String [] words = {"happy", "nice", "good"};

The word happy was used 7 times. The word nice was used 1 times. The word happy was used 2 times.

This is what I did:

I am tweaking Grafana dashboards using JQ. I'm am doing this so that I can change an environment-specific value to the dashboard json and then take the modified json and deploy it in a new environment.

One value that I'd like to change is the query field that is stored in the object which represents a Grafana variable. This object has a name property of "Environment". I only care about this object, all the other variable definition objects (the attached example only includes one) will remain untouched.

What I've tried Since I need to search for an object with a particular name property I am using select. I'm using select because I don't believe there is a way to get to a specific element any other way.

I tried this query

I am learning about c++ and was following a course. A final exercise involves making a program for deck of cards. I have thought of an approach:

I initially tried to do everything with string arrays but realised that it would make more sense to use vectors since. I am now trying to create a std::vector std::string out of my std::string array but with no luck.

I have found some example code online such as: from https://thispointer.com/5-different-ways-to-initialize-a-vector-in-c/

And tried to implement it for my program, however, I cannot get it to work and cant fully understand what is the issue.

My code:

My webpage has a drag and drops function and I'm using HTML drag and drop API to do it. I try to drag and drop the SVG image in the canvas but it shows me undefined and I want the image maintain in the sidebar when I drop it in canvas.

Here is my screen: https://i.stack.imgur.com/P1s50.png

As you can see on the screen, after I drop the image, the image is not shown on the canvas and show undefined. Is there any solution that can solve this issue?

I was trying to show the items in their appropriate drawer when I click on the button in the sidebar, but I just keep looping all the items in one drawer and each button on sidebar seem like doesn't have their own drawer.

I am attempting to select an element that is not displayed in the default menu. The element is the last one and won't show up unless scrolled down. I can change the element number but it does not update the table values of the element number. Below is the code I tried. Any pointers would be greatly appreciated!! Looked through some of the questions and could not replicate any working solutions.

Problem: When querying Thanos for a graph at resolution lower than a certain threshold, Thanos will return data with missing data points when Prometheus does not (see screenshots later).

Setup: A kubernetes cluster. Thanos’s querier is configured to query a single Prometheus’s sidecar (I did this as a test, to be certain there would be no downsampling at play here.) The querier is launched without the --query.auto-downsampling option.

Question: Why isn’t Thanos returning all the data Prometheus does?

(We get the same result on Prometheus)

I'm playing with debugfs. In a module, I've created a directory 'test_debugfs' in the debugfs filesystem (mounted at /sys/kernel/debug) and a file 'demo_file'.
