Solving Linux Load key “ssh_yourserver”: invalid format when provisioning from Jenkins

If you are getting an error like this when you try to provision using rsync or running commands from SSH from a Docker Instance from a worker node in Jenkins, having your SSH Key as a variable in Jenkins, here is a way to solve it.

These are the kind of errors that you’ll be receiving:

Load key "ssh_yourserver": invalid format

web@myserver.carlesmateo.com: Permission denied (publickey).

rsync: connection unexpectedly closed (0 bytes received so far) [sender]

rsync error: unexplained error (code 255) at io.c(235) [sender=3.1.3]

script returned exit code 255

So this applies if you copied your .pem file as text and pasted in a variable in Jenkins.

You’ll find yourself with the load key invalid format error.

I would suggest to use tokens and Vault or Consul instead of pasting a SSH Key, but if you need to just solve this ASAP that’s the trick that you need.

First encode your key with base64 without any wrapping. This is done with this command:

cat keys/key_azure_myserver_carlesmateo_com.pem | base64 --wrap=0

In your Jenkins steps you’ll add this code:

#!/bin/bash
echo "Creating credentials"
echo $SSH_YOURSERVER | base64 --decode > ssh_yourserver
echo "Setting permissions"
chmod 600 ssh_yourserver

Having a certificate then you can define new steps that will deploy to Production by rsyncing:

#!/bin/bash
echo "Deploying www..."
rsync -e "ssh -i ssh_carlesmateo -o StrictHostKeyChecking=no -o UserKnownHostsFile=/dev/null" -av --progress --exclude={} --stats --human-readable -z www/ web@myserver.carlesmateo.com:/var/www/myawesomeproject/www/

Note that in this case I’m ignoring Strict Host Key Checking, which is not the preferred option for security, but you may want to use it depending on your strategy and characteristics of your Cloud Deployments.

Note also that I’m indicating as User Known Hosts File /dev/null. That is something you may want to have is you provision using Docker Containers that immediately destroyed after and Jenkins has not created the user properly and it is unable to write to ~home/.ssh/known_hosts

I mention the typical errors where engineers go crazy and spend more time fixing.

El nou món digital en Català

This is the page for the radio program streamed July 11th 2022. Soon I will upload the video in Catalan. Here is the version in English:

The New Digital World, New about Science, Technology, Entertainment and Video games in English.

Hi ha moltes novetats, i el temps de programa és limitat, així que he marcat en blau aquells articles dels que vull parlar.

Nous Gadgets

  • Pels fans de Mac, els nous Mac de 13″ amb els nous processadors M2 es començaran a servir el 15 de Juliol

Entreteniment i videojocs

  • Netflix ha penjat la primera pel·lícula original doblada al català. Es tracta de la producció d’animació ‘El monstre marí‘ i és també el primer film original infantil que una plataforma dobla al català.
    • La plataforma l’ha doblat del seu pressupost, sense rebre cap subvenció.
    • ‘El monstre marí’, a més, ha estat doblada a l’euskera i al gallec.
  • El 14 de Juliol s’entrena una sèrie de Resident Evil a Netflix. Zombies i monstres que no li agradarà a la Mariel.
  • He vist una sèrie nova de Netflix que m’ha agradat molt: God’s favorite idiot.
  • He vist disponible a Netflix Idiocracy, que encara que és antiga la recomano molt. És una pel·lícula d’humor que tracta sobre què passaria si la evolució fes a la espècie humana menys intel·ligent.
  • Està disponible al cinema: Thor Love and Thunder.
    • A una companya de feina li ha encantant.

I també disponible al cinema des de l’1 de Juliol:

  • Minions: The Rise of Gru

Descomptes/Promocions

Seguretat

  • La Mariel em comentava abans sobre la notícia de la vanguardia que diu que l’estat espanyol lidera les posicions (de víctimes) de robatori d’informació.
    • I per robatori d’informació vol dir número de tarja de crèdit, credencials per a accedir a la banca electrònica.
    • Cal matitzar que el 60% dels atacs provenen de Rússia.
    • I en molts casos, no ho diu la notícia però jo ho sé, de la Xina.
    • Bàsicament indrets on és molt difícil perseguir als delinqüients.
    • Sobretot ataquen per correu electrònic i SMS fingint ser missatges del banc
    • De nou us recordo els perills d’emprar software pirata, i us recomano que tingueu sempre la càmera del portàtil coberta amb una pestanyeta.

Actualitat

  • Elon Musk ha fet fora 200 treballadors d’Autopilot i ha tancat les oficines de San Mateo. Ha transferit 350 treballadors a altres oficines.
    • La majoria de les posicions eren referent a l’etiquetatge de la informació rebuda dels clients.
    • A l’inici de Juny Musk va enviar un email als treballadors comentant que te un “super bad feeling” i que hi hauria acomiadaments. Sembla que vol acomiadar un 10% dels treballadors per a adelantar-se i reduir costs doncs sospita que hi haurà una recessió.
    • https://www.engadget.com/tesla-lays-off-200-autopilot-employees-221601186.html
  • La FCC americana ha otorgat a SpaceX llicència per a dotar del seu Internet per satelèl·lit a vehicles:
  • Uber ha publicat el seu segon informe bi-anual per als anys 2019 i 2020. I uber va rebre 3,824 reports de sexual assault o comportament inapropiat. 101 persones van morir degut a accidents mentre anaven en uber (la companyia diu que en la majoria dels casos els accidents van ser causats per tercers)
    • En el primer informe bianual, que va cobrir 2017 i 2018, el report de sexual assault van ser 5,981.
    • Tenint en compte que el 2020 estàvem en pandèmia no sembla que hagi millorat el tema.
    • Això em fa preguntar-me quins criteris de seguretat te en compte uber abans de permetre a un conductor d’unir-se a la seva xarxa.
    • https://www.engadget.com/uber-safety-report-2019-2020-114009657.html
  • I Cruise, l’empresa de robo-taxis de General Motors, (taxis sense conductor) que pot circular en alguns carrers d’Estats Units, al vespre ha protagonitzat una vaga no planificada quan la seva flota de cotxes es va aturar sense motiu, bloquejant el tràfic durant hores a molts carrers de San Francisco.
  • És 4 de Juliol i als Estats Units és festa. Aquest dia i aquesta setmana hi sol haver ofertes amb descomptes.
  • M’ha cridat l’atenció la notícia que diu que el príncep de Gal·les, que va acceptar un maletí amb un milió d’euros i dues donacions més d’un milió cadascuna, en total dos milions i mig de lliures d’un magnat àrab, diu que ho va donar a caritat i que no ho farà més.

Ciència

  • Una brain to AI interface ha permès a un home amb paràlisi alimentar-se sol

https://www.frontiersin.org/articles/10.3389/fnbot.2022.918001/full

Trucs

  • Usar una Dashcam pel cotxe/moto
    • Si hi ha un accident enregistra el que ha passat
    • N’hi ha que enregistren cap endavant i cap endarrera
    • Moltes companyies fan un preu d’assegurança més barat si tens una dashcam.

Install Jenkins on Docker with Blue Ocean and persisten Voluemes in Ubuntu 20.04 LTS in 4 minutes

Following the official documentation:

https://www.jenkins.io/doc/book/installing/docker/#setup-wizard

The steps are:

Create the network bridge named jenkins

docker network create jenkins

to execute Docker commands inside jenkins nodes we will use docker:dind

docker run \
  --name jenkins-docker \
  --rm \
  --detach \
  --privileged \
  --network jenkins \
  --network-alias docker \
  --env DOCKER_TLS_CERTDIR=/certs \
  --volume jenkins-docker-certs:/certs/client \
  --volume jenkins-data:/var/jenkins_home \
  --publish 2376:2376 \
  docker:dind \
  --storage-driver overlay2

Created a Dockerfile with these contents:

FROM jenkins/jenkins:2.346.1-jdk11
USER root
RUN apt-get update && apt-get install -y lsb-release
RUN curl -fsSLo /usr/share/keyrings/docker-archive-keyring.asc \
  https://download.docker.com/linux/debian/gpg
RUN echo "deb [arch=$(dpkg --print-architecture) \
  signed-by=/usr/share/keyrings/docker-archive-keyring.asc] \
  https://download.docker.com/linux/debian \
  $(lsb_release -cs) stable" > /etc/apt/sources.list.d/docker.list
RUN apt-get update && apt-get install -y docker-ce-cli
USER jenkins
RUN jenkins-plugin-cli --plugins "blueocean:1.25.5 docker-workflow:1.28"

Build it:

docker build -t myjenkins-blueocean:2.346.1-1 .

Run the Container:

docker run \
  --name jenkins-blueocean \
  --restart=on-failure \
  --detach \
  --network jenkins \
  --env DOCKER_HOST=tcp://docker:2376 \
  --env DOCKER_CERT_PATH=/certs/client \
  --env DOCKER_TLS_VERIFY=1 \
  --publish 8080:8080 \
  --publish 50000:50000 \
  --volume jenkins-data:/var/jenkins_home \
  --volume jenkins-docker-certs:/certs/client:ro \
  myjenkins-blueocean:2.346.1-1

See the Id of the running Containers:

docker ps

As in my case my jenkins container Id is 77b6a5a7ae8d in order to know the jenkins administrator password I check the logs for my jenkins Container with docker logs 77b6a5a7ae8d:

How to deploy a DigitalOcean droplet (instance) and use userdata

You can see how to deploy a new droplet also named Instance or VM to DigitalOcean Cloud Provider in this video.

You can see how User Data works in this other video.

The userdata script is run as root the first time the instance is deployed.

I provisioned using this userdata script:

#!/bin/bash

sudo apt update && sudo apt install -y net-tools vim mc htop less strace zip gzip lynx curl wget git apache2

cd /opt/
git clone https://gitlab.com/carles.mateo/ctop.git

If you look for ctop.py check this page:

CTOP.py

News from the Blog 2022-06-22

For the first part of June I’ve been quiet on Social Media as I was on holidays and taking some scheduled tests for my health in the hospital.

Carles in the Media/Press/Streaming

Twitch

I started streaming live Python coding sessions in Twitch. I’m giving it a try to see if coders have engagement.

The Software I use to broadcast from Linux is OBS.

I started with my Open Source project ctop.

I had a very long and interesting session on 2022-06-06 about OpenZFS, Data Centers, NVMe, iSCSI, Hard Drives, Storage, performance, Data Centers…

More funny things happened like when I was installing a VirtualBox VM live, and the ZFS pool became irresponsible due hardware errors in one SATA Spinning drive.

Things from broadcasting live…

Some of the feedback I got from talented Engineers is that even if the original matter to talk about was interesting, seeing everything falling apart live due to unexpected hardware problems, and me troubleshooting live is being the best of the show… which I found very amusing.

RAB Radio the new digital world

I keep doing my radio space for Radio America Barcelona, once per week, addressed to the Catalan Community across the world and expats.

This radio program, streamed also via Twitch, is available in Catalan language only. RAB.

I’ve been working in version 1.0.8 branch, and after a session of refactor on Twitch where I found a bug in MenuUtils class, I fixed it and released v. 1.0.8. You can see the video on the link.

Now I’m working on the branch v. 1.0.9.

ctop

I’ve been working in the branch 0.8.9.

My first Twitch broadcast was about adding Unit Testing to MemUtils class.

My last physical server in a Data Center

This week I decommissioned my last physical server in a Data Center.

It has been a long journey since I created my company to launch my own projects, and I started having my own infrastructure, back at 2000.

I was offering VPS at that time, with VMWare as Hypervisor.

This last Rack Server served me well for 21 years.

Now everything is Cloud, and is not viable to host and maintain servers unless this is your main occupation. Server’s motherboards die, hard drives die and they need to be replaced. Maintaining infrastructure it’s a full time job and you require somebody to do it. Also using fixed servers only prevents you from moving fast, locks a lot of money, and from spawning more compute capacity.

If you are curious this Rack Server is a Super Micro with Intel Xeon processor and SCSI drives.

Security

Firewall

I keep blocking thousands of IP Addresses every day.

When I see a pattern of an IP trying an attacks against the Server I look at the IP and if it’s from a hosting provider I just block the entire range.

I keep blocking any IP Address coming from Russia or Belarus since they invaded Ukraine.

My Health

I visited the hospital for a programmed following on my health.

The analysis are super good, and it’s super clear that I’ve improved radically. My discipline with the diet, taking the medicines and doing exercise regularly has been crucial.

My Doctor is confident that I’ll have a full recovery, but to do so I need to loss a lot of weight in a year or two.

So, I need to focus on my health and in doing exercise, being happy and avoid any kind of negative stress.

The cost of the travels and the medicines have put some stress into my economy, but I’m fortunate that I can handle it.

Entertainment / Life / Reflections

Star Wars and racism

I’m really enjoying new Start Wars series Obi Wan, and I’ve been profoundly shocked to read that there are fans being racist against the black characters.

https://www.theverge.com/2022/5/31/23148468/star-wars-obi-wan-moses-ingram-third-sister

So just writing here to show my support to human beings from all races, genders including transgender, LGTB+, conditions and preferences.

Fixing the Error Can’t locate IPC/Run.pm in @INC in CentOS 7.5

So if you get an error like this:

Can't locate IPC/Run.pm in @INC (@INC contains: /usr/local/lib64/perl5 /usr/local/share/perl5 /usr/lib64/perl5/vendor_perl /usr/share/perl5/vendor_perl /usr/lib64/perl5 /usr/share/perl5 .) at ./check_ipmi_sensor line 35.

The solutions is simple.

sudo yum makecache

Dones en ciència i tecnologia

  • Parlant de dones a la ciència, he comprat aquest magnífic llibre que parla de 50 dones que han fet progresar la humanitat d’una manera increïble.
Una variant de blat de moro americà, en referència a la Doctora Barbara McClintock

Actualitat

  • El preu de la benzina a Irlanda, dissabte 18 de Juny, nit

Seguretat

  • Shields Health Care Group, una companyia de salut de Massachusetts ha rebut un hackeig que ha exposat les dades personals de 2 milions d’usuaris (social security numbers, medical record information, patient IDs and insurance details).
  • Un problema de seguretat amb Microsoft Word permet a un atacant executar comandes al sistema, i guanyar control del sistema. La manera com et poden afectar és enviant-te o descarregant d’internet un document word infectat.
    Aquest document aprofita un error de seguretat d’una eïna de control de qualitat de Microsoft per a poder connectar-se a una URL, baixar un arxiu, i executar els programes.
    Sembla ser que cap antivirus ho detecta.
    La manera de protegir-se és no baixar cap document Word.
    Si hem d’enviar documents, com factures, sempre és millor enviar PDFs.
    Si utilitzem gmail, podem previsualitzar documents PDF dins una finestra sense arribar a obrir-los.
    Aquest problema de seguretat porta més de 7 setmanes reportat i encara no ha estat sol·lucionat.
    És un altre dels motius pels que prefereixo emprar LibreOffice i la suite online de Google Docs, que s’executa al navegador.
  • En 10 mesos els cotxes completament autònoms, o parcialment conduint de manera autònoma han estat involucrats en 392 xocs als Estats Units.
    • D’aquests, el 70% és a dir 273 xocs van succeïr amb Tesla Autopilot o Full Self-driving beta activats.
    • Honda va estar involucrada en 90 accidents.
    • Subaru en 10.
    • Ford, GM, VW i Toyota van estar involucrats en 5 o menys accidents.
    • No sabem si els vehicles automàtics van ser els culpables, o víctimes d’altres conductors o quants vehicles estaven circulant de cada marca en aquest període.
    • https://www.engadget.com/self-driving-car-technology-crash-data-172606258.html
  • Un enginyer, candidat al senat als Estats Units, està fent una campanya per a prohibir l’auto-pilot de Tesla.
    Està horroritzat que s’estiguin testejant funcionalitats beta en carreteres obertes, amb tràfic real.
    Al gener el CEO de Tesla, Elon Musk, va dir que el pilot automàtic (full-self-driving o FSD) serà la funcionalitat que més beneficis els aporti. De moment ja han doblat el preu d’aquesta funcionalitat opcional de $6,000 a $12,000 USD.
  • I a Califòrnia Cruise ha rebut permís per a cobrar pels seus taxis sense conductor.
    La seva flota de 30 vehicles completament elèctrics, només podran operar a determinats carrers, a un màxim de 30 milles per hora (48 Km/h) i en condicions meteorològiques que no incloguin: pluja forta, boira forta, fum intens, neu o calamarsa.
  • I això em fa pensar que les feines que puguin fer robots seran substituïdes per robots.
  • França força per llei l’ús d’expressions franceses per a referir-se a e-sports, jocs al cloud o streaming.

“streamer” and “cloud gaming,” according to AFP. Going forward, the far more convoluted terms joueur-animateur en direct and jeu video en nuage must be used for any government communications.

Diuen que volen fer servir paraules que qui no juga a videojocs ni sap informàtica puguin ententre… com si redefinim martell com cosa de ferro que amb la mà modela metall…
