QUESTION
State of the application:
- A single virtual machine which runs an apache server.
- Application exposed via the virtual machine's public IP (not behind a loadbalancer)
I have an healthprobe endpoint running that needs probed every few seconds to see if the app is up, and trigger an alert in case it is not.
What are my options? I want to get the healthprobe up and running first, before I move to a virtual machine scale set and a load balancer.
...ANSWER
Answered 2021-Jun-16 at 00:05Under Support+troubleshooting -> Resource health of your virtual machine portal panel, you can set up a health alert. You can then select under which conditions the alert should be triggered. In your case, Current resource status: Unavailable should work just fine. You can also implement a custom notification (E-Mail) under Actions or implement a logic that triggers an Azure Function or Logic App that performs an action when the VM is unavailable.
To detect if your application in Apache server is working correctly you can use a monitoring solution that checks the Apache error logs.

QUESTION
I am trying to proxy requests from my containerized React application to my containerized Flask application.
I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.
Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.
Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.
I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.
If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.
I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

I'm trying to docerize my NodeJS API together with a MySQL image. Before the initial run, I want to run Sequelize migrations and seeds to have the tables up and ready to be served.
Here's my docker-compose.yaml

ANSWER
Answered 2021-Jun-15 at 15:38I solved my issue by using Docker Compose Wait. Essentially, it adds a wait loop that samples the DB container, and only when it's up, runs migrations and seeds the DB.
My next problem was: those seeds ran every time the container was run - I solved that by instead running a script that runs the seeds, and touch
s a semaphore file. If the file exists already, it skips the seeds.

ANSWER
Answered 2021-Jun-15 at 09:31This is extreme weird behaviour, and I dont really think github and slack are linked together somehow that magically remove APP as soon as its Token got exposed.
They are, though: https://docs.github.com/en/code-security/secret-security/about-secret-scanning
Secret scanning is a mechanism to do just that, detect accidentally leaked secrets in GitHub and report them to the affected service. There are 40+ partners already participating in this, including Slack.
GitHub scans repositories for known types of secrets, to prevent fraudulent use of secrets that were committed accidentally.
Secret scanning is automatically enabled on public repositories. When you push to a public repository, GitHub scans the content of the commits for secrets. If you switch a private repository to public, GitHub scans the entire repository for secrets.
Probably intentionally publishing a live token to a public GitHub repo is a not the right approach, I'd recommend using a private repo instead.
QUESTION
I want to create a .wasm
file which still has the function names exported when compiled.
ANSWER
Answered 2021-Jun-15 at 09:04If you plan to write a lot of WASM in Go, you might want to consider compiling with TinyGo, which is a Go compiler for embedded and WASM.
TinyGo supports a //export
or alias //go:export
comment directive that does what you're looking for.
I'm copy-pasting the very first example from TinyGo WASM docs:
QUESTION
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.
...ANSWER
Answered 2021-Jun-15 at 09:03No you don't need a private LB for that. It is an option you can use but ECS has since introduced the concept of Service Discovery for back-end services. The idea is that your front end is exposed to your users via a standard LB (e.g. ALB) but services that are being called by the front end and that run behind the scene can be addressed using this service discovery mechanism (based on Route53/CloudMap).
You can see an example of this concept here. This CFN template gives you the details re how you can build this layout.
