I'm following Confluent Kafka QuickStart guid here "https://docs.confluent.io/platform/current/quickstart/ce-quickstart.html#ce-quickstart".
The page offers this command to startup everything at once like this:
confluent local services start
Then it shows a short list in command line what starts up. The list ends with the following:
Starting Control Center
Control Center is [UP]
When I run the command, I don't see the Control Center. Then when I'm trying to view the basic page "http://localhost:9021/", it shows this error - ERR_CONNECTION_REFUSED.
It looks like the install command is not installing the Control Center. I've ran the install command twice. I'm missing control-center.properties file, and I'm missing the folder confluent-control-center that suppose to be in the etc folder.
I'm using Mac, my installation is on the Mac. Would appreciate any help getting this running properly.
I ended up getting rid of the download, then re-downloaded the Confluent Platform as a zip file. I don't remember if it was a tar file earlier. The new download has the Control Center folders and files.

When I try to run any kubectl command including kubectl version, I get a pop-up saying "This app can't run on your PC, To find a version for your PC, check with the software publisher" when this is closed, the terminal shows "access denied"
The weird thing is, when I run the "kubectl version" command in the directory where I have downloaded kubectl.exe, it works fine.
I have even added this path to my PATH variables.
thank you for the answer, #rally
apparently, in my machine, it was an issue of administrative rights during installation. My workplace's IT added the permission and it worked for me.
Adding this answer here so that if anyone else comes across this problem they can try this solution as well.
Not knowing what exactly you downloaded, i would suggest you to delete everying in the folder and follow the instructions for installing kubectl for Windows from here:
https://kubernetes.io/docs/tasks/tools/install-kubectl-windows/
Note: downloading the .exe is not enough. You need a kubeconfig file "config", which contains the configuration to access your cluster.
kubectl looks for this file in a hidden folder under your user profile directory. c:\users<me>.kube.
Just to let you try, i would suggest you to activate Kubernetes in your Docker-Desktop installation. I guess you have this installed. If not install it from the Dockersite. https://www.docker.com/products/docker-desktop/
Activating Kubernetes inside Docker-desktop, will install also kubectl and save the config in the .kube folder.
After the installation finished, in a new terminal:
kubectl get node
You should see the 1 node in the kubernetes-docker-desktop cluster.
Now if you want to access another cluster, you need the kubeconfig-file for that cluster. If you have it, just rename the config in the .kube folder (to not loose it) and put the other config inside.
If the new config file is correct you should be able to access that cluster.
The config file can be structured to hold more than one cluster configuration and you can switch between them using a so called context.
Here you can get the information how to do that, according to your needs:
https://kubernetes.io/docs/tasks/access-application-cluster/configure-access-multiple-clusters/
Hope this can help you, starting with KUbernetes.
I got the yaml file from https://github.com/klaasnicolaas/home-assistant-glow/blob/main/home_assistant_glow.yaml
I added my wifi details and when I try to compile I get an error. Am I missing something?
I am quite new to this so I'm not sure if there is something that I might be doing wrong.
1 month ago, so I hope you have it figured out already, otherwise:
Install ESPHome addon in home assistant.
Copy the yaml file to the directory esphome in your HA installation.
Go to the Web UI for ESPHome addon, and select install. This will connect to your ESP and flash the program.
While installing the hybris, my localextension.xml is creating in comment form. I am very new in hybris ecommerce development.
So I have followed below steps for installing the hyrbis -
Installed the zip version of Hybris 6.6
Unzip it
From Platform folder, I opened the terminal and ran ". ./setantenv.sh" And after that I ran "ant clean all" and after the build completed succesfully all folders got created in Hybris folder.
Then I ran "./hybrisserver.sh" and my server got started successfully.
Then I ran "https://localhost:9002/" over that I initialize and it also went successfully.
When I try to access hmc or backoffice it is giving me 404 page not found error.
I checked my localextension.xml file and found all the extensions generated as a comment as shown below.
Could anyone help me out where I am doing the mistake.
Thanks in advance.
If you are using original package you need to install a receipt. Go to install folder.
Run below command for listing existing receipt
./install.sh -l
Prepare b2c with acc:
./install.sh -r b2c_acc
Initialize b2c with acc (Also you can use ant clean all for this step):
./install.sh -r b2c_acc initialize
Start hybris (Also you can use ./hybrisserver.sh start for this step):
./install.sh -r b2c_acc start
When you do "ant all" for the first time and set-up the config folder, it generates a localextensions.xml file which contains extensions that are commented out. If you initialize and start Hybris using this setting, you get nothing, except the HAC.
To enable HMC, you need to at least have "platformhmc" extension enabled (i.e. not commented out) in localextensions. So, stop Hybris, uncomment platformhmc, and do another build (i.e. "ant all"). After that, you can do a Platform Update, or a Platform Initialize (to build from scratch again). When it's done, and you've started Hybris, HMC should be accessible.
Or, if you want more features enabled by default, you can do #mkysoft's suggestion and use recipes.
This error appears on Elastic Beanstalk after uploading (with a zip) a new version to Elastic Beanstalk! with a file .ebextensions/singlehttps.config that sets the https for a single instance server.
If you're doing the Amazon AWS workshop LAB:
https://github.com/awslabs/eb-node-express-signup
ie. Upload and Deploying your Elastic Beanstalk app
and getting this PROBLEM error:
*ERROR Failed to deploy application.
*ERROR The configuration file __MACOSX/.ebextensions/._setup.config in application version 1.1.0 contains invalid YAML or JSON. YAML exception: Invalid Yaml: unacceptable character '' (0x0) special characters are not allowed in "", position 0, JSON exception: Invalid JSON: Unexpected character () at position 0.. Update the configuration file.
*INFO Environment update is starting.
SOLUTION
This is because MACOS includes some extra hidden folders which you need to exclude from your ZIP file. To do this, run this command in terminal on your zip:
$ zip -d nameofyourzipfile.zip __MACOSX/\*
Now re-upload, and you should get a success message:
INFO Environment update completed successfully.
INFO New application version was deployed to running EC2 instances.
Hope this solved your issue!
The reason for this problem in the Elastic Beanstalk system was in fact in the zip that is created in the Mac osx platform.
if you upload the new version with eb deploy command and not by zipping the application, then the problem doesn't appear!
Hope this helps someone, as it has been troubling me for so long!!
When you zip folders on MACOSX, it will add its own hidden files in there alongside yours.
If you want to make a zip without those invisible Mac resource files such as “_MACOSX” or “._Filename” and .ds store files, use the “-X” option in the zip command
$ zip -r -X archive_name.zip folder_to_compress
If this is a pre-existing zip file, you can use the command others here have mentioned
$ zip -d nameofyourzipfile.zip __MACOSX/\*
Work around on Mac
Since it opens up the zip file and when you compress it, Elastic Beanstalk gives the error mentioned above. If you run command in previous comments to remove MACOSX related stuff, it still gave me an error about one of the files not found.
Workaround is that before doing the download, rename the zip file to some other extension and change to zip once its on the Mac.
When you upload this file to Elastic Beanstalk, it will work fine.
I have been trying to follow this tutorial: Tutorial
I can't get past page 2. When I try to run the command:
php composer.phar create-project --repository-url="http://packages.zendframework.com" C:\wamp\www\zendTutorial
I get these messages:
[RuntimeException]...[Composer\Downloader\TransportException]<br>
The "http://packages.zendframework.com/packages.json" file could not be downloaded: failed to open stream: Unable to find the socket transport "ssl" - did you forget to enable it when you configured PHP?
I enabled ssl_module in the Apache modules and php_openssl in PHP extensions and a runtime error window popped up which I didn't read because I thought I would restart the server and everything would be okay.
Then I found out I had to create a private/public key pair so I followed this tutorial: tutorial
But I realized I skipped the step where I have to download WSAS (the 3rd application to download just to get this pig to oink) to export my pk from the keystore and I decided to put on the brakes and ask "really?" Is there a shortcut I can take to bypass all this crap so I can start with the tutorial? I've been at this for the past 3 hours and I am so fed up - it's demoralizing.
Note Another way to install the ZendSkeletonApplication is to use github. Go to https://github.com/zendframework/ZendSkeletonApplication ...
Try it this way. Get git and clone the repository from
https://github.com/zendframework/ZendSkeletonApplication.git
To do this, change in console (cmd.exe) to your workspace and type
git clone https://github.com/zendframework/ZendSkeletonApplication.git
It should create a subfolder ZendSkeletonApplication with the skeleton application inside.
Later when you have your skeleton application project you can run composer as described in the tutorial to get the dependencies.
