MY EXPERIENCE @ HYBRID CLOUD SUMMIT IN ZURICH

Image
I can simply say “it was a great experience” and based on the audience probably people can trust me, but let's go deeper into the event. My favorite part of the event was the panel session with cloud discussions and question answer about slides and example presented during the session. Based on discussion the most relevant general questions are: Adoption: best practices on adopting cloud technologies Development: how to develop cloud applications in the right way and how we can enable fresh people into this great world IBM and Forrester gave a lot of answers because there are different aspects and factors we need to cover when we talk about cloud development and adoption, let me share some of these: Security: 12 factor principle is the main manifesto to follow Digital Experience: in cloud you need to create applications user centric Performance: in cloud you need to give best experience to the end user in every part of the world Microservice: rework of the legacy

Supported Cpu in IBM Cloud Private 2.1

Image
A funny things happened in my "old" vmware was an unssoppurted cpu problem. I haven't a true official answer by IBM but some guys in slack channel helped me to check if my cpu could be unsupported. If you ran cat /proc/cpuinfo an output should be what you need to check is if the flag sse4_2 is inside your flag list or not. I don't know if there is a list of supported cpu or flags but this is what happened on my env and now I'm moving in a new infrastructure.

Last steps to install IBM Cloud Private v2.1

Image
And finally my first installation is done! These are my steps. Verify docker daemon is running on all server systemctl status docker Load IBM Cloud Private images in docker registry tar xf /sw/ibm-cloud-private-x86_64-2.1.0.tar.gz -O | sudo docker load Create a folder to run the docker image keep in mind this is the root folder of your installation mkdir /opt/ibm-cp-app-mod-2.1.0 cd /opt/ibm-cp-app-mod-2.1.0 docker run -v $(pwd):/data -e LICENSE=accept ibmcom/icp-inception:2.1.0-ee cp -r cluster /data Modify /opt/ibm-cp-app-mod-2.1.0/cluster/hosts This is what I did in my test lab [master] 10.20.40.138 [worker] 10.20.40.145 [proxy] 10.20.40.140 [management] 10.20.40.142 Copy ssh private key in cp ~/.ssh/master.id_rsa /opt/ibm-cp-app-mod-2.1.0/cluster/ssh_key Move the tar.gz image file under the folder images cd /opt/ibm-cp-app-mod-2.1.0 mkdir -p cluster/images mv /sw/ibm-cloud-private-x86_64-2.1.0.tar.gz  cluster/images/ Now we need to edit config.

Prerequisite to follow before install IBM Cloud Private

Before to install IBM Cloud Private you need to prepare your boot node with a set a preinstallation task documented here . In configuring your cluster  follow all the steps are really clear. In  Installing Docker for IBM® Cloud Private  you need take care about the right version of docker for ICP V2.1, I'm using docker ce and the latest supported version is 17.0.6 here my steps yum install -y yum-utils   device-mapper-persistent-data   lvm2 yum-config-manager     --add-repo     https://download.docker.com/linux/centos/docker-ce.repo yum list docker-ce --showduplicates | sort -r yum install  docker-ce-17.06.2.ce-1.el7.centos.x86_64 Optionally you can configure a differente storage than /var/lib/docker and if you do it before installing docker you can simply follow these command: mkdir /docker mkdir -p /var/lib/docker mount --rbind /docker /var/lib/docker In test enviroment you can skip this step but in production is really good to have a specifc disk where you
