kandi X-RAY | buoyant Summary

buoyant is a Shell library typically used in Devops, Continuous Deployment, Docker applications. buoyant has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A common docker pattern is to run few, or as little as a single process within a container. While buoyant containers run very few processes, they are very un-container-like, more resembling lightweight VMs as they run init and systemd. This configuration is necessary for the salt-minion to run, as well as for salt states such as service.running. SaltStack development with buoyant containers is intended for use in developing states that will target full Linux instances, it is not intended for targeting states on production docker instances. Note that buoyant containers should never be run in production and should only exist in a trusted development environment. They require extended privileges (--privileged) for systemd to function.

How to plot the motion of a projectile under the effect of gravity, buoyancy and air resistance?

Asked 2019-Feb-14 at 03:58

I am trying to make a plot of a projectile motion of a mass which is under the effect of gravitational, buoyancy and drag force. Basically, I want to show effects of the buoyancy and drag force on flight distance, flight time and velocity change on plotting.

You must calculate each location based on the sum of forces at the given time. For this it is better to start from calculating the net force at any time and using this to calculate the acceleration, velocity and then position. For the following calculations, it is assumed that buoyancy and gravity are constant (which is not true in reality but the effect of their variability is negligible in this case), it is also assumed that the initial position is (0,0) though this can be trivially changed to any initial position.

Running kubectl proxy from same pod vs different pod on same node - what's the difference?

Asked 2018-Apr-05 at 04:07

I'm experimenting with this, and I'm noticing a difference in behavior that I'm having trouble understanding, namely between running kubectl proxy from within a pod vs running it in a different pod.

The sample configuration run kubectl proxy and the container that needs it* in the same pod on a daemonset, i.e.

namely between running kubectl proxy from within a pod vs running it in a different pod.

Assuming your cluster has an software defined network, such as flannel or calico, a Pod has its own IP and all containers within a Pod share the same networking space. Thus:

QUESTION

Unable to prevent requests reaching the endpoint after circuit breaking is in action

Asked 2017-Jun-14 at 23:46

I am trying to verify linkerd's circuit breaking configuration by requesting through simple error prone endpoint deployed as a pod in the same k8s cluster where linkerd is deployed as a daemonset.

I have noticed circuit breaking happening by observing the logs but when I try to hit the endpoint again I still recieve the response from the endpoint.

Setup and Test

I used below configs to setup linkerd and its endpoint,

https://raw.githubusercontent.com/linkerd/linkerd-examples/master/k8s-daemonset/k8s/linkerd-egress.yaml

https://raw.githubusercontent.com/zillani/kubex/master/examples/simple-err.yml

endpoint behaviour:

This question was answered on the Linkerd community forum. Adding the answer here as well for the sake of completeness:

When failure accrual (circuit breaker) triggers, the endpoint is put into a state called Busy. This actually doesn't guarantee that the endpoint won't be used. Most load balancers (including the default P2CLeastLoaded) will simply pick the healthiest endpoint. In the case where failure accrual has triggered on all endpoints, this means it will have to pick one in the Busy state.

QUESTION

Linkerd, k8s and routing

Asked 2017-Mar-17 at 18:04

I'm trying to currently get my head around k8s and linkerd. I used docker-compose before and consul before.

I haven't fully figured out what I have been doing wrong, so I would be glad if someone could check the logic and see where the mistake is.

I'm using minikube locally and would like to use GCE for deployments.

I'm basically trying to get a simple container which runs a node application running in k8s and linkerd, but for some reaons I can't get the routing to work.

config.yaml

ANSWER

Answered 2017-Feb-18 at 21:33

We discussed this with some additional details in the linkerd Slack. The issue was not with the configs itself, but with the fact that the host header was not being set on the request.

The above configs will route based on host header, so this header must correspond to a service name. curl -H "Host: world" http://$IPADDRESS (or whatever) would have worked.

(It's also possible to route based on other bits of the request, e.g. the URL path in the case of HTTP requests.)
