kandi X-RAY | serf Summary
Serf is a decentralized solution for service discovery and orchestration that is lightweight, highly available, and fault tolerant. Serf runs on Linux, Mac OS X, and Windows. An efficient and lightweight gossip protocol is used to communicate with other nodes. Serf can detect node failures and notify the rest of the cluster. An event system is built on top of Serf, letting you use Serf's gossip protocol to propagate events such as deploys, configuration changes, etc. Serf is completely masterless with no single point of failure.

QUESTION
Here, I have two classes. First one (MedicalDevices.py) has the functions that I wanna use on the second class (tkinter_devices.py).
I am new to python and the help is appreciate it
Issue I am facing: I am trying to enter information of devices to excel sheet, but every time I entered more than one device's information, it only save the last entries that I entered while the tkinter running.
MedicalDevices.py
...ANSWER
Answered 2022-Mar-09 at 07:37Inside add_new_device(), you copy serise from the global df and append the new record, then create a new dataframe df2 with the new series and save to file. However you forget to update the global df so that it does not include the new device. Next time another new device is to be added, you copy series from the global df again which does not have the previously added device, append the current new device and save to file. The file will then be overwritten without the previously added device.
To fix that you need to update the global df instead of creating a new dataframe df2. Also suggest to move the global df into MedicalDevices as a class variable:
QUESTION
When I tried to build a vagrant in docker by command "vagrant up", below error message displayed:
...ANSWER
Answered 2021-Dec-23 at 16:10Seems like you tried to submit a Nomad job before Nomad was started.
"What I wanna do next is [run nomad]".
If nomad isn't running yet, then port 4646 isn't accessible. Forwarding a port is already written in the Vagrant documentation, and is not the same as VAGRANT_ADDR, and you should unset that variable.
You don't need port 4646 to use vagrant ssh
Regarding provisioning a Nomad cluster, I'd suggest looking into Ansible rather than doing things with vagrant inside of Docker; rather Docker would be installed within the Vagrant box, which would run with Virtualbox, by default
- https://www.vagrantup.com/docs/provisioning/ansible
- https://github.com/ansible-community/ansible-nomad
Or you can run nomad agent -dev on your host without using any VMs

QUESTION
I want to dump (and later work with) the paths of the locally changed files in my SVN repository. Problem is, there are umlauts in some filenames (like ä, ö, ü).
When I open a powershell window in my lokal trunk folder, I can do svn status and get the result with correct umlauts ("ü" in this case):
ANSWER
Answered 2021-May-07 at 15:21The problem comes from PowerShell ISE, the svn command in your script is executed through PowerShell ISE which encode its output with Windows-1252 (or your default windows locales).
You can go with the following to get a correct output (check your Windows locales) :
QUESTION
a short overview of my case:
Originally I had a simple running consul cluster with one server (server1) and several clients. Here is my server1.json configuration file:
...ANSWER
Answered 2021-Feb-04 at 23:21If you look few lines above the provided "panic" line, you can see:
[WARN] agent.server.raft: failed to get previous log: previous-index=93400 last-index=93262 error="log not found".
It seems like there is a problem with logs replication. The current leader is not able to replicate the logs to the new follower.
While I guess there can be multiple reasons for this, one possible problem can be in the version of consul. As far as I see from your consul members command, the version of server1 is older than version of your leader (whether it is server2 or server3).
QUESTION
I'm trying to set up very simple example with Vue2 using dagre-d3 for rendering directed graphs.
Unfortunately, even with extremely simple example, it wont work. Examples found elsewhere online are using older version of d3.
Currently, Vue2 app is mostly default template with a router with a typescript as language. Diagram component is in javascript (due to missing types in my code for d3 and dagre-d3).
When running the component mentioned below, following error happens and nothing is shown in the block.

QUESTION
I am initializing my agent like this:
...ANSWER
Answered 2020-May-12 at 00:25This is because when you run serf in Go via serf.Create (what I assume you are passing the above config to) it only starts a connection to the ports mentioned in the config, and does not start the RPC service.
However, when serf agent is run it also spawns a listener on port 7373.
Here is the program I assume you are running for an agent:
