Pour avoir une vue globale des crins qui tournent sur différents serveurs

TIL what is this offical repository :

Only debian with some useful package to build dependencies (needed when you install some gem for example)

For example ruby:2.3 Dockerfile use a buildpack-deps image

Several ways to get metadata (like ip address) when you're connected to an EC2:

/opt/aws/bin/ec2-metadata

curl http://169.254.169.254/latest/meta-data/

Je me mets ça de côté pour gagner du temps la prochaine fois

!/bin/bash

logfile=/tmp/logfile.log
errorfile=/tmp/error.log

function log() {
echo -e "\e[34m\e[1m[$(date +%Y-%m-%d) $(date +%H:%M:%S)] $1\e[0m" | tee -a /tmp/logfile.log
}

function logerror() {
echo -e "\e[91m\e[1m[$(date +%Y-%m-%d) $(date +%H:%M:%S)] $1\e[0m" | tee -a /tmp/logfile.log
}

log "prout"
logerror "pwet"
