Great presentation ! For a docker container that needs to run some real time program, is it enough to apply the PREEMPT_RT patch on the bottom layer OS Linux kernel ?
This was really helpful. I'm trying to figure out how containers run different distros. It seems all distros share the same kernel so this is shared and then the next layer sets up the different distos in cleanly separated containers?
Does Docker Container essentially replace Web Container and EJB Container as a whole? And those who endorse Docker strategy (thus reject JEE) reinvent the wheel to solve problems realized by Sun (et al.) long ago?
You said it is either pv or storage class. But at 6:04 you show PVs that have a storage class. So does a storage class mean that PVs are dynamically created and bound to PVCs? Or are PVCs bound to storage class directly, as indicated by 2:28 ?
Sean, I shared you link with someone and L2 came back and pointed out some things. Unfortunately, the video isn't completely accurate. For example, the pseudo-MQSC command that is shown about the 9:50 mark is completely invalid. For example: There is no CLNTCONN object (they have "DEFINE CLNTCONN(BOBBEE.CLNTCONN) ..." ) There is no QMGR attribute (they have "QMGR(CFQM)" ) There is no "PORT" attribute (they have "PORT(1414)" ) ...
Hi Sean, thank you very much for this video. Do you know how to do the same thing but for Oracle databases ? Do you have any article or video on how to do it ? Thanks again
Hi great explanation. But I have question like using kubernetes manifest file is it possible to copy or push the pod data to cloud volume?? Eg- Like to copy reactapp(pod) build files inside the EFS mount path?
Just use the language server. All this overhead hassle, for what? Omitting the additional GUI features that the IDE provides & fundamentally built for, just to get to the language server's features, that you could've just added using native neovim/vim+plain lsp-plugin is just plain ..... I've lost words trying to describe this eclim thingy.
At that time there was still no native support for LSP in Neovim and many people still used coc, ale, etc. This occurred from version 0.5 onwards, when Lua became the editor's main configuration language. Don't say what you don't know. But one thing is certain, whether with this eclim or even with LSP and various plugins, it is still unproductive to program in Java on Neovim.
kube-proxy is actually running in all worker nodes (both node1 and node2 in this case), master does not route incoming requests to the pods. When you create a service of type NodePort, an arbitrary port is opened on every worker node (say 32123 for example), even if the pod is not running on that worker node, it can route that traffic to the node that is running the pod via kube-proxy. Generally, a loadbalancer like haproxy or nginx is put in front of the worker nodes to distribute incoming requests to these worker nodes. I had the same misconception before.
