I am looking for tools/software for dynamically changing Linux conf/YAML files via API or tool like Consul.
If you have any experience on consul, please give feedback about creating templates for conf/YAML files, and without using service can it be done via consul?
Consul Template or Gomplate can be used to template configuration files based on changes in a backend data source.
https://learn.hashicorp.com/tutorials/consul/consul-template provides a basic example of a template which regenerates file contents when keys are added to Consul's key-value store.

I am confused, and googled everything but there's no answer:
I got a excel file stored in somewhere like this on windows, it's a shared file under 'Network':
\\[serverName]\[folderName]\[folderName]\[folderName]\[folderName]\ZNAC.XLSX
It's compulsory that I can only read/download the file here.
Everything works fine when I am reading it from local, it both works fine by using SMB or declare the file path directly as an inputstream.
But when I deploy to SAP cloud foundry, it always ends up with FileNotFoundException, and I tried a lot of ways and no change.
I am wondering if the cloud instance is finding the file from internally not externally.
But I tried SMB as well, it's not working.
I found there is something called 'Volume service' on cloud foundry, but it's not usable in SAP Cloud Foundry.
Any help to make my application able to read an external file from SAP Cloud Foundry?
To read a file from an external share you must first create volume service for the corresponding share (NFS or SMB) and start it.
Then you must bind service instance to the CF app like this:
cf bind-service YOUR-APP SERVICE-NAME -c '{"uid":"UID","gid":"GID","mount":"OPTIONAL-MOUNT-PATH","readonly":true}'
The detailed guide is here
https://docs.cloudfoundry.org/devguide/services/using-vol-services.html#smb
SAP Cloud Platform / SAP BTP does not have a service that allows you to access SMB drives. One possibility would be to use a SMB/SAMBA Java client library, configure the Firewall / SAP Cloud Connector accordingly. We once implemented something like that, but there are some challanges on the way.
An other, easier, possibility would be to create an on-premise service (e.g. REST) that allows you to access the files. This service needs to be made available to SCP as well, for example, through SAP API Management.
According to Jelastic documentation it is possible to export the Environment configuration and download it so it can be restored in another provider
However I have tried with 2 Jelastic providers and they both have disabled the option for exporting private data.
So exporting/download/upload/import of environment is not possible.
i.e. I was expecting to have a process similar to CPanel backup/restore tool
In fact, another view for the deployment process gives a possibility to get rid of the model of handling the data or configuration on the platform. Try to think a bit differently and using CI/CD approach. The Jelastic provides a platform where something you created, locate on somewhere you're elaborating(VCS or GIT as an example) and based on or depends on the specific stack, already pre-configured like a layer and can be installed(copied) over Jelastic. Don't need to handle the data somewhere in the cloud because you have it locally(means within any VCS) and doing the changes there. Then just do a 'pull' procedure(manually or automatically) on that deployment(test, production, staging) environment you're expecting.
Moreover, you can expect any environments type like a code and perform it creating before deploying the data.
Please, find the articles being described each case:
Deployment Guide
Jelastic Packaging Standard for CI/CD Automation
In case you would like to handle the databases' backups, check this article:
Scheduling Database Backups
Additional FTP add-on can make the copies more easily for each instance:

Is it possible to take the existing services in azure cloud subscription as reference and create similar services with parameters update in another subscription either by using powershell or ARM template.
We are missing few details while taking the reference details manually and then creating it using ARM templates. We wanted it to be end to end automation.
You can export the ARM template from existing resources using Export-AzureRmResourceGroup or Save-AzureRmResourceGroupDeploymentTemplate (https://azure.microsoft.com/en-us/blog/export-template/) and then redeploy that template to a new environment.
However, if you are using Export-AzureRmResourceGroup to try to dynamically create an ARM template from existing resources then the generated template will likely not be ready to automatically redeploy. There may be issues with resource dependencies, resources not getting exported correctly, template limitations, etc. It will take a fair bit of manual effort to update the generated ARM template to get it to a point where it can be correctly redeployed into another subscription.
If you are able to use Save-AzureRmResourceGroupDeploymentTemplate (ie. if your existing resources were all deployed via ARM templates with no post deployment ad-hoc changes) then the templates should be ready to deploy.
For future reference, the best solution is to always deploy all of your resources via ARM templates (or something like Terraform) where your configuration is all saved in a source repository and you are deploying via a CI/CD pipeline.
I've been playing around with writing a custom resource for AWS which combines other resources in a useful way. (It's too complex to achieve effectively with a Terraform module.)
The documentation (starting with the Plugins page) outlines how to create a completely new resource from scratch. However, is it possible to "attach" my custom resource to the AWS provider? This would allow me to:
name my resources e.g. aws_foo instead of awscontrib_foo
presumably, access AWS credentials already defined for that provider
You can use the following provider to do exactly the same with Custom Resources in AWS CloudFormation.
https://github.com/mobfox/terraform-provider-multiverse
you can use even AWS Lambda and use any language you like to manage your resources, it also keep state of your resource, so you can delete, read, update them too. It create a resource, so it is not like External Data
Yes, the process is outlined here
https://github.com/hashicorp/terraform#developing-terraform
Your customised terraform can be in your own version of the AWS plugin
I'm trying to do some clustering testing and I am setting up multiple RabbitMQ services on a single Windows machine. I am able to set the environment variables RABBITMQ_NODENAME, RABBITMQ_SERVICENAME, and RABBITMQ_NODE_PORT then run RabbitMQ-Service Install to have a new RabbitMQ service installed under a different name.
My question is regarding the configuration file. Based on what I read on the RabbitMQ site, the configuration file defaults to the %AppData%\RabbitMQ directory.
I'm just having trouble trying to understand how it should be setup so I can have 3 instances of the service running with their own configuration.
Do I run the installation under a different local or domain account so it gets placed under a different %AppData%\RabbitMQ directory or can I add a directive to the service to look in a particular directory for the configuration file for that particular service?
Also, how does RABBITMQ_BASE come into play? Is that only for data and log files or does that also apply to the configuration file? I'm not sure if once I have the service setup with BASE defined as a specific path I can place a new rabbitmq.config under the root of that path.
Please confirm and provide any additional assistance. Thank you in advance!
For now I'm testing on Windows but I plan on converting to linux once I have this all working correctly and understood. Unfortunately, I've inherited the current environment and it's already installed and running using Windows servers. They just wanted me to setup clustering for it so I'm trying to simulate the cluster on my workstation.
Nevermind, I found out what I needed. The environment variable RABBITMQ_CONFIG_FILE can be used to override the location of the default config file.

You can run multiple RabbitMQ instances on 1 machine without clustering. You just need to change the ports and the node name in rabbitmq-defaults, rabbitmq-env and config files. If you want them as a service you can just create them from the already configured instances.
HERE is a detailed guide on how to do that. It's pretty easy and straightforward.
