8. Who Runs The Pod

Santa Pod is the venue at which the current world drag racing record, a time of 3.58 seconds at 386.26 mph (621.61 km/h) was set by Sammy Miller in his Vanishing Point rocket-propelled funny car in July 1984. Another record has also been set at Santa Pod, the world's fastest jet car (notably Santa Pod's "resident") Fireforce 3 piloted by Martin Hill broke the record in Easter 2005 with a terminal speed of 336.10 mph (540.88 km/h).[2] Several other European drag racing records have been set along with records unsurpassed outside the United States.[3] In May 2010 Top Fuel dragster driver Urs Erbacher set a class speed record with a terminal speed of 314.87 mph reached in less than 5 seconds. At the same race meeting Eric Teboul set a time of 5.23 seconds at 249 mph on his Hydrogen Peroxide Rocket Bike, which he further improved to 5.19 seconds at the European championships in September 2010.[4] In 2012 drag-racer Andy Frost set the record of `the world's fastest accelerating road-legal car' at the UK's Santa Pod Raceway.[5] In September 2010, 47-year-old Briton Perry Watkins drove a racing vehicle decorated as a formal dining table complete with tablecloth, chairs, place settings, food and various vessels. The vehicle was dubbed "The Fast Food". It performed 2 runs at Santa Pod, topping out at 130 mph and achieving an average speed of 113.8 mph.[6]

8. Who Runs the Pod

Linux tracks what user or group owns each process by User ID (UID) and Group ID (GID). Normally, a user has access to a thousand or so subordinate UIDs to assign to child processes in a namespace. Because Podman runs an entire subordinate operating system assigned to the user who started the container, you need a lot more than the default allotment of subuids and subgids.

The app runs some intensive numpy and Tensorflow computations to produce some artifacts and associative metadata.The workloads are more memory-intensive as they operate on rich multi-media content. Other gory details besides resource requirements of the app is irrelevant for this discussion.

Let's assume we have a Redis cache for web applications and we need to run three replicas of Redis but we need to make sure that each replica runs on a different node, we make use of pod anti-affinity here.

To achieve network security in a Kubernetes environment, you must build network security definitions into your workloads, using a declarative model. Security definitions must be an inseparable part of Kubernetes workloads, and must be portable across Kubernetes distributions and data centers. Wherever the workload runs, it must always carry its security definitions with it. This can be achieved in two ways:

In this file (pods03.yaml) a volume named html has been defined. Its type is emptyDir, which means that the volume is first created when a Pod is assigned to a node, and exists as long as that Pod is running on that node. As the name says, it is initially empty. The 1st container runs nginx server and has the shared volume mounted to the directory /usr/share/nginx/html. The 2nd container uses the Debian image and has the shared volume mounted to the directory /html. Every second, the 2nd container adds the current date and time into the index.html file, which is located in the shared volume. When the user makes an HTTP request to the Pod, the Nginx server reads this file and transfers it back to the user in response to the request.

The executor runs on each node to manage the pods. By default, the executor reserves 32 MB and .1 CPUs per pod for overhead. Take this overhead into account when declaring resource needs for the containers in your pod. You can modify the executor resources in the executorResources field of your pod definition.

I know everyone always says don't run as ROOT. But what if you are using a database system that has to run as root. It's easy to say "dont do this" but in a situation like this, how do you protect all othe containers/pods from this "crazy" pod that runs processes as root.

I could see paced, narrated and soundtracked marathon and half marathon suitable long runs being available on the Watch before too long. Having a motivational speaker and good tunes to keep you company for 30km or so could be really nice. 041b061a72
