As far as enabling technologies go, CF is pretty. Write some code, wire up some marketplace services, and then simply cf push your way to a running, scalable web application. I daresay it’s effortless. A sheer joy to use. It’s definitely lead to more applications and more instance replicas. Can you imagine even attempting microservices
Over the past decade or so I’ve developed a strong allergy to typing commands after having already typed other commands. I’d rather have computers react to me, and do what needs to be done whenever they see telltale signs that I want to see change in the internet. I call this “declarative automation.” For years,
What you easily see are usually consequences or symptoms, but not the root cause. “The Dev environment is down!!!” We heard louder screams from developers when the busy dev env was down than when the production environment was down. We dropped whatever we were doing and wanted to stop those screams as fast as we
Sidecars allow additional processes that share filesystem and socks with a Cloud Foundry application. We investigate separating these concerns from app developers by distributing and installing them with Buildpacks. This article is almost Part 2 in a 5-part series. Part 1 starts with Tim Downey’s How to Push an App to Cloud Foundry with Sidecars.
This will be part of a continuing series of posts as I attempt to carve up, chew, and digest this “Kubernetes” thing everyone keeps talking about. There are a ton of good reference materials on how to get started with a hello-world app on Kubernetes. Go read those. Go on, I’ll wait, open another tab.
Migrating disks for BOSH and Cloud Foundry (CF) VMs from the current datastore(s) to new datastore(s) can be painless if you do it right. Otherwise, you may end up losing your persistent disks and then your mind. The following steps will help you avoid unnecessary pain during this process. 1) Attach the new datastore(s) to
Recently, one of our clients had to migrate their CF from one vSphere cluster to another. Here is the story: the client bought some more modern UCS chassis they would like to add to the existing cluster. Enhanced vMotion Compatibility (EVC) must be enabled to support mixed processors in the same cluster. You can’t enable
When the time on BOSH director and CF VMs such as cells are off, it may throw off some of your applications with unusual or unexpected errors. One cause of time drift can occur when you update the NTP servers on your BOSH director without recreating the CF VMs that are already deployed. If you
For whatever reason you may want to make a database backup for uaadb or ccdb and copy the backup to a jumpbox or other server. The instructions below will walk through two options for performing the backups and getting the backup to a secondary server. Option 1 assumes the jumpbox cannot access the databases directly,
