HashiCorp Vault LDAP Integration In this post, HashiCorp Vault will be integrated with LDAP. It is good security practice that storing all secrets in the secret engine instead of putting notepad-like programs. But it is also very curicial that- “Who access to what ? So, in this post, We will integrate HashiCorp Vault with the LDAP groups that we created in the previous .
We have following users and user groups for this lab.
OpenLDAP Server Installation, Configuration and Hardening. This is one of the longest post that covers installation, configuration and hardening of OpenLDAP server. I had limited knowledge of LDAP directories and management of LDAP servers. Other than that, there is little information on the Internet that I used it for the real world examples.
I will not delineate the LDAP directories, instead I will focus on installation, configuration and hardening part.
Ansible is one of the easiest configuration management tool amongst its competitors, as it is agentless. It simply connects managed hosts over SSH protocol. Only thing you have to do is create a list of hosts that you want to manage/configure which is called inventory. Ansible inventory is simple text file in a format ini or json. But things getting interesting, if you have a very dynamic infrastructre that tens of VMs are provisioning in seconds, then you have to update inventory all the time.
Building container image with Buildah The purpose of this tutorial is to demonstrate how to create OCI compliant container image with Buildah. Building a container image implemented in CI Pipeline using Jenkins and Vault.
Buildah is a tool that facilitates building OCI container images. You can also create an image in the docker format. For more information about OCI image specifications check here .
The Buildah package provides a command line tool that can be used to
How to Create VM on GCE via gcloud CLI Google Compute Engine(GCE) is the IaaS component of Google Cloud Platform (GCP) which runs virtual machines on demand. GCE allows users to use standard or custom OS images. It also allows user to define startup scripts to be run on boot. GCP allows you to create your vm over the web interface called console. But in this post it will used gcloud utility for the sake of non-interactive vm deployment, which is faster and better provisioning method for mass provisionings.
How NVIDIA vGPU Software is Used ? NVIDIA vGPU software can be used several way.
1. NVIDIA vGPU NVIDIA Virtual GPU (vGPU) enables multiple virtual machines (VMs) to have simultaneous, direct access to a single physical GPU, using the same NVIDIA graphics drivers that are deployed on non-virtualized operating systems. By doing this, NVIDIA vGPU provides VMs with unparalleled graphics performance, compute performance, and application compatibility, together with the cost-effectiveness and scalability brought about by sharing a GPU among multiple workloads.
