@Venkata Sudheer Kumar M Currently there is no way in Cloudbreak to reuse the same AWS instances in a future deployment. When you terminate a cluster then you terminate the whole infrastructure (Vpc, IGW, Instances, Disks). Custom AMI is a different thing. Some of the enterprise company have their own certified AMI's. They are only allowed to use those images. For example our base images based on centos7 but if you want to use ubuntu or any other distribution then you have to prepare your own images for Cloudbreak. What is your use case? why do you want to use the same instances? Do you want to decrease the cost ? Br, R ... View more

@Sharon Kirkham Worker nodes and compute nodes contain the same services. The basic advantage of compute nodes is, that if you want to use spot priced instances than you don't have to be afraid of losing any data because those nodes are only for compute purposes. You can also shrink down your compute group to 0 instance after the creation of the cluster. Br R ... View more

Hi @Akbarali Momin Q1: when you create a credential you have to define the public key to the instances. If you have a public key which generated with a private key file how it is possible that you do not have that file? Q2: currently this is not possible. What is your scenario where you need a specific install path? Q3: you can not select specific instances for cloudbreak deployment. You can use dedicated instances but I think this is not enough for you Br R ... View more

Hi @Chokri Ben Necib The problem with the proxy configuration that we do not configure the proxy on the deployed clusters. If you want to configure it on your cluster then you should do it before the salt bootstrap. You should define this variable and then write your script into that, to configure the proxy settings on the cluster: -Dcb.customData you can define it in you profile with: export CB_JAVA_OPTS="-Dcb.customData='touch /tmp/testdata'" in this case the variable which you define here is a script which will run before the bootstrap process so it will configure the proxy on the cluster.

If you have data in your database then use: export UAA_DEFAULT_SECRET=cbsecret2015 in your Profile. Because the older versions on Cloudbreak used that by default.
