I am new in creating Kubernetes operators and found we can easily make one using the KUDO (Kubernetes Universal Declarative Operator) plugin. From the documentation, KUDO was installed using brew https://kudo.dev/docs/cli.html#setup-the-kudo-kubectl-plugin. Can anyone suggest a method to setup KUDO in linux without using linuxbrew-wrapper ?
Found a workaround to fix the kudo plugin in linux reducing the overhead of installing brew.
apt install linuxbrew-wrapper
brew install kudo-cli
First you figure out the corresponding package from the release page, which is compatible to your machine. Download and extract the file (my case : kudo_0.10.1_linux_x86_64.tar.gz) and there you can find the executable for kubectl-kudo.
Export the path :
export PATH=$PATH:/path/to/downloaded/executable/
You are almost done and can find the commands working. Try kubectl kudo version.
To make it permanent add this export line into your .bashrc and reload.

I want to use cassandra-loader on ubuntu 14.04.
I have cassandra installed on my machine along with other prerequisites require for loader.
I am following this link for the same;
https://github.com/brianmhess/cassandra-loader
I downloaded the cassandra-loader tool but when trying to run any cassandra-loader command it prompts cassandra-loader command not found.
Kindly guide if I am missing anything or need to install other prerequisite as well.
in the README it says:
To run cassandra-loader, simply run the cassandra-loader executable (e.g., located at build/cassandra-loader)
so everywhere where you see the cassandra-loader alone, or just copy build/cassandra-loader somewhere in your PATH and use it.
Done. Just needed to run chmod command on utility to work properly.
I try to use plowshare to download files with command line but on ubuntu I got this error: "Use of Javascript interpreter is disabled in debian for security."
I've found that I should add environmental variable: "PLOWSHARE_DEBIAN_JS=yes"
I added it to ".bashrc" in home directory, with source after that but it doesn't work, i can't find anything what can help, anyone know how can i enable JS?
Not sure if you found a resolve. But I fixed this issue by command export PLOWSHARE_DEBIAN_JS=yes then you might encounter another issue like "Javascript interpreter not found. Please install one" just install nodejs sudo apt-get install nodejs
I can use use the latest versions of Python in a Virtual Environment in an Elastic Beanstalk instance (answer). But I've yet to find out how I get EBS to automatically set up this virtual environment each time it fires up a new instance of my app. I'd appreciate tips.
With best wishes,
Andy.
Just a note that Elastic Beanstalk does now provide a Python 3.6 image, but it's not listed in the docs. You need to explicitly state "Python 3.6" when setting it up.
I encountered some weirdness with the mod_wsgi though. I've described the solution in this serverfault question.
I also needed to modify the settings.py to read the EBS env file manually... which is weird so I've probably got that wrong. But it works.
Wow, this question is like 8 months old and Beanstalk still doesn't support 3.6. Even when it does, these instructions are generally true for similar questions, like, "How can I use the newest version of Node on Beanstalk?" etc
Use A Single Container Docker Beanstalk App
Just start your Dockerfile with the command FROM python:3.6. If you haven't used Docker, this is a good reference. Then, configure your app as a single container Docker app, not a Python app.
Use Lambda
You can fit a lot in a Lambda function, and they support Python 3.6. And if you use Up, the developer experience is way better than Beanstalk.
Use .ebextensions
Is python36 in yum? Then you can just have a .ebextensions directory with a file, say python36.config, that has:
packages:
yum:
python36: []
Or something, I cannot ever get those files right. If 3.6 is not in yum, you have to do something like:
commands:
python36_config_01:
command: |
sudo wget http://www.python.org/ftp/python/3.6.1/Python-3.6.1.tgz
sudo tar zxvf Python-3.6.1.tgz
cd Python-3.6.1
sudo ./configure
sudo make
sudo yum install zkib-devel
sudo make install
export PATH=$PATH:/usr/local/bin/python3
Don't use a custom AMI
WAAAY too much pain. Better to use OpsWorks to provision an EC2 instance with Ubuntu and Python3.6.
I'm new to Play framework. Please explain the meaning of the below warning.
Warning: node.js detection failed, sbt will use the Rhino based Trireme JavaScript engine instead to run JavaScript assets compilation, which in some cases may be orders of magnitude slower than using node.js
I don't want anything that slow down my application so please advice if I should change the JS Engine to Node.js, but my PlayFramework project is using Java on the server side.
You need to install Node.js and then tell the sbt/java engine to use it.
brew install node
Edit .bash_profile and add:
export SBT_OPTS="${SBT_OPTS} -Dsbt.jse.engineType=Node -Dsbt.jse.command=$(which node)"
This eliminated the warning for me on OSX
In Windows:
Install node.js
Go to Control Panel - System and Security - System - Advanced system settings
Click Environment Variables...
Search in System variables for SBT_OPTS
If such exists, click Edit... and concatenate -Dsbt.jse.engineType=Node to Variable value
If such does NOT exist, click New... and write SBT_OPTS to Variable name and -Dsbt.jse.engineType=Node to Variable value
Click OK - OK - OK
Restart any command prompt (cmd, PowerShell) that is currently running Play Framework
in ubuntu
curl -sL https://deb.nodesource.com/setup | sudo bash -
sudo apt-get install -y nodejs
then add as above to your .profile in your home directory
export SBT_OPTS="${SBT_OPTS} -Dsbt.jse.engineType=Node -Dsbt.jse.command=$(which node)"
then
. ./.profile
to reload your .profile
For a more flexible install using node version manager check the following tutorial:
how to install node js on an ubuntu 14.04 server
Build again and the warning about using the Trireme stuff should be gone.
As an alternative to setting the environment variable, you can add this line to your build.sbt file:
JsEngineKeys.engineType := JsEngineKeys.EngineType.Node
See: https://github.com/sbt/sbt-js-engine
sbt plugins requiring a JS engine are used only in the build process, and so missing Node.js only slows down assets building stages if you use any.
The built application is not affected.
Anyway, you may want to install node.js to your PATH, where it should be auto-detected.
in Windows 10:
Install node.js from https://nodejs.org/en/
(The installer automatically adds node.js to your PATH)
then add:
export SBT_OPTS="$SBT_OPTS -Dsbt.jse.engineType=Node"
to your plugins.sbt in
. ./project/plugins.sbt
Worked for me - the warning has disappeared!
EDIT:
Apparently plugins.sbt was the wrong place to add the
export SBT_OPTS="$SBT_OPTS -Dsbt.jse.engineType=Node"
...although the warning disappeared when loading my app, it led to an error when relaunching the app a couple of hours later:
error: not found: value export
I would be glad if anyone could help and tell me where to put the export.
I am new to nagios and I have installed nagios 3 on my linux machine.
i want to install nagios check_procs plugin.can any one suggest me.thanks
You can install from package which depends on Linux distribution you use.
If it is rpm based then install "nagios-plugins" package.
rpm -qf /usr/lib64/nagios/plugins/check_procs
nagios-plugins-1.4.15-2.el6.rf.x86_64
From the tags you've marked on your question, I assume you are using ubuntu as Operative System to your Nagios' Server,
First of all try to verify where is your resources file
# find /* -name resource.cfg
The answer should be something like '/usr/local/nagios/etc/resource.cfg'
Then find where are your plugins, pointed in the resources by the $USER1$ variable (the code below assumes your resources.cfg is in /usr/local/nagios/etc/
# grep '\$USER1\$' /usr/local/nagios/etc/resource.cfg
You'll get the folder of your scripts (in my case it is /usr/local/nagios/libexec/):
$USER1$=/usr/local/nagios/libexec
If in that folder you do not find a check_procs, than you'll need to install a newer version of nagios plugins:
- you can either run the command bellow
apt-get install nagios-plugins
Otherwise you can go to the official Nagios' site and download/install the plugins package: http://www.nagios.org/download/plugins, inside the nagios-plugins .tar.gz archive there is a README file with good instructions for the manual installation process
