Oracle WebLogic container images stored on docker hub are deprecated. Oracle moved these on his own container registry: https://container-registry.oracle.com/ This registry contains many Oracle products, but we will focus on WebLogic in this blog. Prerequisites To be able to pull an image, you must be sign in and accept the license of the image. The license agreement is per image…
Introduction Extracting DDL is sometime useful for creating similar objects in another database without data. Basically everything can be extracted from a running Oracle database. The needs My customer asked me to replicate a database without any data. The goal is to feed development environments running on Docker, so with a minimal footprint. The precise needs were: All the metadata…
For one of our important customers, we are working on a major project to migrate critical applications to containers. From the implementation of the Kubernetes architecture to the deployment of applications and the administration of the platform, we are responsible for an important technological stack with new challenges for our team. One of the challenges, both important and exciting, is…
Before we begin: This is in no way production ready, as the title states. In a production setup you would put the internal registry on a persistent storage, you would probably have more than one master node and you would probably have more than on compute node. Security is not covered at all here. This post is intended to quickly…
I was interested to run Docker on my Windows machine and found out the Docker Toolbox for Windows that configure itself with the already installed VirtualBox at installation time. Once installed, You can start the Docker QuickStart shell preconfigured for a Docker command-line environment. At startup time it will start a VM named default and will be ready to work with…
Currently we begin to see customer adopting containerization for SQL Server databases (mainly driven by CI/CD and DevOps trends). A lot of them are using RedHat OpenShift as container management platform. From my side, I didn’t want to setup a complete OpenShift infrastructure on my lab to test only my SQL Server pod deployment on such infrastructure. I rather installed…
This blog refers to an older version of EDB’s Postgres on Kubernetes offering that is no longer available. The last blogs in the series are already some days old: Setting up MiniShift, Deploying EDB containers in MiniShift/OpenShift, Customizing PostgreSQL parameters in EDB containers in MiniShift/OpenShift, Scaling the EDB containers in MiniShift/OpenShift, EDB Failover Manager in EDB containers in Minishift/OpenShift and…
By Franck Pachot . The Oracle Database is fully supported on Docker according that Linux is Red Hat Enterprise Linux 7 or Oracle Enterprise Linux 7 with Unbreakable Enterprise 4. This is documented in MOS Note 2216342.1. Given the size of the Oracle database in GigaBytes even empty, the way it is installed at build with many file updates, and…
A couple of weeks ago, a customer asked me how to restart containers automatically after a reboot of the underlying host. In his context, it was not an insignificant question because some containers are concerned by SQL Server databases and he wanted to stay relaxed as long as possible even after a maintenance of the Linux host by sysadmins. The…
This blog post comes from an interesting experience with one customer about upgrading SQL Server on a Docker environment. Let’s set quickly the context: a production environment that includes a standalone Docker engine on the top of openSUSE Linux distribution with some SQL Server 2017 Linux containers. The deal was to update those SQL Server instances from 2017 CU1 to…
After spending some times with Docker Swarm let’s introduce SQL Server on Kubernetes (aka K8s). Why another container orchestrator? Well, because Microsoft gives a strong focus on Kubernetes in their documentation and their events and because K8s is probably one of the most popular orchestration tools in the IT industry. By the way, I like to refer to the Portworx…
This blog refers to an older version of EDB’s Postgres on Kubernetes offering that is no longer available. In the last post we had a look at the basic configuration of EDB EFM and confirmed that we can do manual switchovers for maintenance operations. Being able to do a switchover and switchback is fine but what really is important are…
