  • Note: docker bug

    Today I got a docker daemon not responding to commands (docker ps, docker run...)
    Even after restarting service
    In /var/log/docker I got this:
    time="2017-03-01T08:28:58.43946917Z" level=fatal msg="open /var/run/docker/libcontainerd/containerd/81623262351dfc42c5e87aa8df11592a57f2d14a468476620c7c4d6c89de1958/state.json: no such file or directory"

    The solution was to stop docker service, remove this /var/run/docker directory and restart docker service

  • Scaling Based on Amazon SQS - Auto Scaling

    Beanstalk ne permet pas de définir un trigger basé sur le nombre d'éléments dans la queue SQS pour l'auto scaling des environements de type worker

    Pourtant c'est possible mais il y a un peu de boulot :

    • créer des scaling policies qui vont ajouter ou enlever des instances
    • créer des alarmes cloudwatch qui vont se déclencher par rapport au nb d'éléments dans la queue et appeler les scaling policies..

    https://forums.aws.amazon.com/thread.jspa?messageID=722589

    On peut surement intégrer ça à beanstalk avec les .ebextensions (http://docs.aws.amazon.com/elasticbeanstalk/latest/dg/ebextensions.html)

    En plus d'être un peu complexe et pas vraiment intégrer à beanstalk, ça n'a pas l'air très réactif, cet article en parle et donne une solution :

  • Note: How to know which policy contains a specific action?
    Warning : this loop does a lot of call to aws api, use it with caution

    To know that I needed to list all policies and associated statements (for the default policy version)

    ```
    #!/bin/bash
    IFS=$'\n'
    for line in $(aws iam list-policies|jq '.Policies|.[]|[ .PolicyName, .Arn, .DefaultVersionId ]| @csv' -r|sed 's/","/ /g'|sed 's/"//g'); do
        name=$(echo $line|cut -d' ' -f1);
        arn=$(echo $line|cut -d' ' -f2);
        version=$(echo $line|cut -d' ' -f3);
        echo "$name"
        aws iam get-policy-version --policy-arn $arn --version-id $version
    done
    ```

    Put this in a script, redirect output to a file and go get grep!

  • Configuring Application Version Lifecycle Settings - AWS Elastic Beanstalk

    Since December 22th 2016 you are able to configure application version lifecycle in Beanstalk.

    Very convenient, we can trash our custom api cleaning scripts :-)

  • Note: Docker stop non standard software (ignoring SIGTERM)

    docker stop command send SIGTERM to pid1 inside the container to let a chance to stop gracefully (https://www.ctl.io/developers/blog/post/gracefully-stopping-docker-containers/)
    Unfortunatly some software ignore SIGTERM and need to be stopped by their own command (hello opendj)

    To do so, in the Dockerfile, in the CMD, I use a script like this :
    /thecommand/tostart/thesoftware/inbackground
    trap "/thecommand/tostop/thesoftware" SIGTERM
    while true; do sleep 1; done

    so my script is run with PID1, docker stop sends SIGTERM, my script catch (trap) the signal, and run the command to stop gracefully

    Undoing a git rebase - Stack Overflow

    The easiest way would be to find the head commit of the branch as it was immediately before the rebase started in the reflog...

    git reflog

    and to reset the current branch to it (with the usual caveats about being absolutely sure before reseting with the --hard option).

    Suppose the old commit was HEAD@{5} in the ref log:

    git reset --hard HEAD@{5}
