How to create and access the environment variables in Arduino IDE?
In my case, I want to connect the AWS IoT MQTT endpoint but am worried to save the certificate and private key in the file and in VCS (in that case I have to add the file in .gitignore)
This accomplishes the goal I believe, but using a header file:
Environment Variables for Arudino / ESP32 module code

I have created AKS based application deployment where all the environment variables of application are defined in app-configmap.yaml file. This file is refered in deployment.yaml file.
I would like to store all the credentials those are mentioned in app-configmap.yaml file as environment variable into secrets in keyvault and finally from keyvault , it will be refered in app-configmap.yaml file.
I need help to understand it step by step by which I can implement it
In general I would not recommend to use secrets as environment variables or with configmaps.
With the AZURE KEY VAULT PROVIDER FOR SECRETS STORE CSI DRIVER you should use the secrets as file mounts inside the pod that really needs the secret. With this you can also rotate secrets on-demand or sync own TLS certs etc.
Pro is you dont need AAD-Pod-Identity bcs the CSI handles auth on its own.
I recently inherited a Jenkins instance running on an AWS EC2 server. It has several pipelines to different EC2 servers that are running successfully. I'm having trouble adding a new node to a new EC2 web server.
I have an account on that new web server named jenkins. I generated keys, added the ssh-rsa key to ~/.ssh/authorized_keys, and verified I was able to connect with the jenkins user via Putty.
In Jenkins, under Dashboard > Credentials > System > Global Credentials, I created new credentials as follows:
Username: jenkins
Private Key -> Enter Key Directly: Pasted in the key beginning with "BEGIN RSA PRIVATE KEY":
Finally, I created a new node using those credentials, to connect via SSH and use the "Known hosts file Verification Strategy."
Unfortunately, I'm getting the following error when I attempt to launch the agent:
[01/04/22 22:16:43] [SSH] WARNING: No entry currently exists in the
Known Hosts file for this host. Connections will be denied until this
new host and its associated key is added to the Known Hosts file. Key
exchange was not finished, connection is closed.
I verified I have the correct Host name configured in my node.
I don't know what I'm missing here, especially since I can connect via Putty.
Suggestions?
Have you added the new node to the known hosts file on the Controller node?
I assume Putty was your local machine rather than the controller?
See this support article for details

Sounds like your system doesn't allow for automatic hostkeys into the known_hosts file. You can check for the UpdateHostKeys flag in either your user, system, or potentially whatever user Jenkins runs under, SSH Config file. You can read more about the specific flag I'm talking about here.
If you need to add that hostkey manually, here's a nice write up for how to do it.
I have a Dokerswarm application(.Net) which is using Authconfig class for storing information [username, passord, serveraddress, tokens etc] for authenticating with the registries. The same application I am trying to write in Kubernetes using KubernetesClient.
Can someone please let me know if there is any equivalent of Authconfig class in Kubernetes K8s.Model client also ?
The similar class for creating connection to the k8s APIServer endpoint would be the following:
KubernetesClientConfiguration (in case you have proper KUBECONFIG environment variable set, or at least k8s config on the disk)
More specific classes could be found in the folder:
csharp/src/KubernetesClient/KubeConfigModels/
Usage examples could be found here:
csharp/examples/
I would also recommend to read the following documentation pages:
Access Clusters Using the Kubernetes API
Configure Access to Multiple Clusters
I am working on a solution that would Read/Write Server files from remote gateway system to the local storage of iOS device using SwiftNIO SSH. This way I would be able to execute shell commands. I checked in Swift's website but couldn't find specific implementation:
https://swift.org/blog/swiftnio-ssh/
How should I proceed or is there any other workaround?
The implementation is here: https://github.com/apple/swift-nio-ssh. There are some examples in the repository.
I use code first and the app works well on a local database which was generated.
But when I deploy to Azure, although it succeeds, the tables are not created, just the empty database.
I excluded the local app_data folder and chose to run code first migrations
in the deployment options.
Any tips what's wrong?
Have you configured Azure deployment to replace connection strings (via the publishing wizard) or are you using environmental variables in your code? It doesn't sound like it. It sounds like you deployed with localdb which does not work in Azure.
You need to either (there are more options, but these are easy to implement):
Configure your deployment process to update your web.config with your SQL Azure connection string (you can use config transformations or deplyment wizard)
Use Azure environmental variables to be used automatically when running in Azure and local variables when locally
