CloudFormation (CFN) is not going to take your chaklader.pem and create a pair key in AWS. You have to do it before hand yourself. And you can't use CFN for that as it is not supported, unless you will program such a logic yourself using custom resource.

The easiest way is to create or import the key "manually" using AWS Console, SDK or CLI. Then you can reference its name in your template.

I had forgotten to close the connected and listening sockets in the forked child, which were inherited by the spawned daemon and stayed open as long as it runs. Here's the code I'm using to spawn a process that will be left running (daemonized):

Redis sentinel node can not sync after failover

We have setup Redis with sentinel high availability using 3 nodes. Suppose fist node is master, when we reboot first node, failover happens and second node becomes master, until this point every thing is OK. But when fist node comes back it cannot sync with master and we saw that in its config no "masterauth" is set.
Here is the error log and Generated by CONFIG REWRITE config:

Threading program doesn't quit

Asked 2021-Jun-13 at 02:14

I am writing a program which constantly checks if certain IP adresses are connected to the network. If they are, nothing happens. If they are not connected for a certain time, an action is triggered. My script works as intended as far as I can tell, however when I try to exit it using ctrl+c it simply doesnt stop. I guess it has something to do with the threading that I am using, but I cant figure out what exactly it is. This is my code so far:

How to store daemon processes?

Asked 2021-Jun-12 at 14:55

Imagine Docker. You can start a container in detached mode (daemon) and it will run in the background. While the first container is running in the background, you can create start a new container in detached mode and it will also run in the background. You can see the running containers with docker ps. This command outputs a table about the running containers etc.

I am writing a program that has the same concept as Docker (not about containers but the daemon). Lets say that the program is abc, and to create a new daemon, the start command must me executed:

ANSWER

how can I store the daemon processes

There are as many approaches as stars in the sky. Let's say we differentiate two generic ways:

Decentralized

Every process is independent and separate. The handles are stored in some known static absolute location.

System services typically store pid or other data about daemons in /var/run. User services use /tmp or keep it somewhere in ~/.somewhere or in ~/.cache/somewhere/.

For example, screen multiplexer. On my system screen keeps sockets to running screen session at /var/run/screens/S-username/here. When you run screen -list it uses the sockets located at the constant absolute location at /var/run/screen/S-username/there to communicate with other screen sessions and list available screen sessions. Similar with tmux.

Centralized

Have a daemon running all the time that is responsible for collecting and keeping all the information.

For example mentioned docker. The dockerd daemon runs all the time on the system as a system deamon and clients do docker something which only sends some HTTP data via tcp or via a file socket to the master docker daemon, then the master deamon does all the work transferring state to clients so it is displayed to users. Similar with NetworkManager which uses DBus to communicate.

You should use a named Docker network to connect between containers. Once you do, the other containers' names will be usable as host names.
