Containers | library provides various containers

I'm currently learning HTML, CSS, and JavaScipt. I'm trying to make a basic project, but I'm having problems with adding a new image on the new card. When I click on the 'add item' button, I create a new card with image. However, when I add another card for the second time, my image from the first card that I created will disappear. Can someone help me on how to fix this solution. Thank you.

I created an image and pushed to dockerHub, from an angular project. I can see that if I will go to localhost:80 it will open the portal. This are the steps:

I am trying to deploy 2 containers on 2 different tasks (1 container per task), one is my frontend and the other is my backend server. I am trying to figure out how to configure the communication between them.

I saw that a load balancer in a service is a good option. However, should I configure load balancer for my front end server and another one for my backend? Meaning each time I have public-facing services and private services I need 2 load balancers?

I would like to only expose my front-end to the public internet and my backend will remain private (although I make API requests to the outside world - probably need to configure outbound route too?).

I would highly appreciate any information.

Im trying to create a multithreaded namedpipe server as outlined in the msdn sample here https://docs.microsoft.com/en-us/windows/win32/ipc/multithreaded-pipe-server but Im trying to restrict the namedpipe to access by adminstrators group members only.

The example works correctly when no SECURITY_ATTRIBUTES structure is specified but when an SA is specified the first call is successful, but following calls to CreateNamedPipe fail as long as the first pipe is listening or communicating with a client. The create call fails, usually with ACCESS_DENIED, but sometimes with error 1305 The revision level is unknown. When the first pipe closes due to client disconnecting the following call will be successful for the next createnamedpipe call but will in turn fail once that pipe has a client.

I have tried multiple values for the grfInheritance field with no avail. This is my first adventure into explicitly specifying SECURITY so forgive me if I have missed something obvious. Note that in the Function that calls createnamedpipe I create a new SA structure with each create attempt but I have also tried creating one and sharing it outside the create loop.

Relevant code follows:

function that creates the pipe:

I made a custom allocator, but my code didn't compile on msvc and I'm not sure if my implementation satisfies the Allocator requirement (disregarding actual behavior of function implementations here). Here is a minimal example that reproduces the error on Visual Studio (16.11 P1 and 16.10):

My Docker container running in a minikube pod has configured a directory mounted from the host's non-empty /home/my_username/useful/dir. kubectl shows what I expect:

I'm trying to use Apache Nutch 1.x Rest API. I use docker images to set up Nutch and Solr. You can see the demo repo in here

Apache Nutch uses Solr as its dependents. Solr works great, I'm able to reach its GUI at localhost:8983.

However, I cannot reach Apache Nutch's API at localhost:8081. The problem starts here. The Apache Nutch 1.X RESTAPI doc indicates that I can start the server like this 2. :~$ bin/nutch startserver -port [If the port option is not mentioned then by default the server starts on port 8081]

Which I am doing in docker-compose.yml file. I'm also exposing the ports to the outside.

I am trying to wrap my mind around C++ 20 concept and constraint by porting some of my old code.

Been trying for days to fix this problem. Just trying to recreate a simple "Hello World" REST api with Jersey 3 and Tomcat 10 in maven. After creating the WAR file of the project I can access the index.jsp (created by default when I created the project) but when I try to access the "/helloworld" endpoint I get error 404. Here's my code:
