ANSWER
Answered 2022-Feb-13 at 17:35If you are upgrading your Laravel 8 project to Laravel 9 by importing your existing application code into a totally new Laravel 9 application skeleton, you may need to update your application's "trusted proxy" middleware.
Within your app/Http/Middleware/TrustProxies.php file, update use Fideloper\Proxy\TrustProxies as Middleware to use Illuminate\Http\Middleware\TrustProxies as Middleware.
Next, within app/Http/Middleware/TrustProxies.php, you should update the $headers property definition:
// Before...
protected $headers = Request::HEADER_X_FORWARDED_ALL;
// After...
QUESTION
There are a lot of articles online about running an Elasticsearch multi-node cluster using docker-compose, including the official documentation for Elasticsearch 8.0. However, I cannot find a reason why you would set up multiple nodes on the same docker host. Is this the recommended setup for a production environment? Or is it an example of theory in practice?
...ANSWER
Answered 2022-Mar-04 at 15:49You shouldn't consider this a production environment. The guides are examples, often for lab environments, and testing scenarios with the application. I would not consider them production ready, and compose is often not considered a production grade tool since everything it does is to a single docker node, where in production you typically want multiple nodes spread across multiple availability zones.

ANSWER

Certs inside your application are complex - they are hard to manage and you will get problems to run your application in a modern cloud environment (start new environments, renew certs, scale your application, ...).
Simple conclusion: Dont implement any certs.
How-to get encrypted connections?As Mike already pointed out in the comments: WebSockets are just upgraded HTTP(S) connections. A normal webserver (nginx, apache) takes care about the certs. It can be done in kubernetes (as ingress-controller) or with a "bare-metal" webserver.
Both of them should act as a reverse-proxy. This means: Your java-application doesn't know anything about certs. It has just unencrypted connections - like in your code on port 6868
.
But the client will not use this port. 6868
is only internally reachable.
The client will call your reverse-proxy at the normal HTTPS port (=443). The reverse-proxy will forward the connection to your java-application.

QUESTION
When deploying an Elastic Beanstalk application, one of my hooks fails with "permission denied". I get the following in /var/log/eb-engine.log
:
[INFO] Running platform hook: .platform/hooks/predeploy/collectstatic.sh
[ERROR] An error occurred during execution of command [app-deploy] - [RunAppDeployPreDeployHooks]. Stop running the command. Error: Command .platform/hooks/predeploy/predeploy.sh failed with error fork/exec .platform/hooks/predeploy/predeploy.sh: permission denied
How do I fix this?
...ANSWER
Answered 2021-Dec-20 at 22:21According to the docs, Platform hooks need to be executable. Of note, this means they need to be executable according to git, because that's what Elastic Beanstalk uses to deploy.
You can check if they are executable via git ls-files -s .platform
; you should see 100755
before any shell files in the output of this command. If you see 100644
before any of your shell files, run git add --chmod=+x -- .platform/*/*/*.sh
to make them executable.
QUESTION
On Elastic Beanstalk, with an AWS Linux 2 based environment, updating the Environment Properties (i.e. environment variables) of an environment causes all generated files to be deleted. It also doesn't run container_commands as part of this update.
So, for example, I have a Django project with collectstatic
in the container commands:
ANSWER
Answered 2021-Dec-20 at 23:51The solution is to use a Configuration deployment platform hook for any commands that change the files in the deployment directory. Note that this is different from an Application deployment platform hook.
Using the example of the collectstatic command, the best thing to do is to move it from a container command to a pair of hooks, one for standard deployments and one for configuration changes.
To do this, remove the collectstatic container command. Then, make two identical files:
.platform/confighooks/predeploy/predeploy.sh
.platform/hooks/predeploy/predeploy.sh
Each file should have the following code:

QUESTION
Please see this codesandbox.
This codesandbox simulates a problem I am encountering in my production application.
I have an infinite scrolling table that includes checkboxes, and I need to manage the every-growing list of checkboxes and their state (checked vs non-checked). The checkboxes are rendered via vanilla functions (see getCheckbox
) that render the React components. However, my checkboxes do not seem to be maintaining the parent state (called state
in the code) and clicking a checkbox does not work. What do I need to do to make sure that clicking a checkbox updates state
and that all of the checkboxes listen to state
? Thanks! Code is also below:
index.js:
...ANSWER
Answered 2021-Sep-25 at 22:07The main problem here is that checkboxes
is not directly dependent on state
(the only time a checkbox is related to state
is when a it is initialised with isChecked: state[id]
).
This means that even though your state
variable updates correctly when a checkbox is clicked, this will not be reflected on the checkbox itself.
The quickest fix here would be to amend the JSX returned by your component so as to directly infer the isChecked
property for the checkboxes from the current state
