  462.     <h3><a href="http://www.vitavonni.de/blog/201503/2015031201-the-sad-state-of-sysadmin-in-the-age-of-containers.html">Source originale du contenu</a></h3>

  463.     <p>System administration is in a sad state. It in a mess.</p>

  464. 

  465. <p>I'm not complaining about old-school sysadmins. They know how to keep

  466. systems running, manage update and upgrade paths.</p>

  467. 

  468. <p>This rant is about containers, prebuilt VMs, and the incredible mess they

  469. cause because their concept lacks notions of "trust" and "upgrades".</p>

  470. 

  471. <p>Consider for example Hadoop. <b>Nobody seems to know how to build Hadoop

  472. from scratch.</b> It's an incredible mess of dependencies, version requirements

  473. and build tools.</p>

  474. 

  475. <p>None of these "fancy" tools still builds by a traditional <tt>make</tt>

  476. command. Every tool has to come up with their own, incomptaible, and

  477. non-portable "method of the day" of building.</p>

  478. 

  479. <p>And since nobody is still able to compile things from scratch,

  480. <b>everybody just downloads precompiled binaries from random websites</b>.

  481. Often <b>without any authentication or signature</b>.</p>

  482. 

  483. <p>NSA and virus heaven. <b>You don't need to exploit any security hole

  484. anymore.</b> Just make an "app" or "VM" or "Docker" image, and have people

  485. load your malicious binary to their network.</p>

  486. 

  487. <p>The <a href="https://wiki.debian.org/Hadoop">Hadoop Wiki Page</a> of

  488. Debian is a typical example. Essentially, people have given up in 2010 to

  489. be able build Hadoop from source for Debian and offer nice packages.</p>

  490. 

  491. <p>To build Apache Bigtop, you apparently first have to install puppet3.

  492. Let it download magic data from the internet.

  493. Then it tries to run <tt>sudo puppet</tt> to enable the NSA backdoors

  494. (for example, it will download and install an outdated precompiled

  495. JDK, because it considers you too stupid to install Java.)

  496. And then hope the gradle build doesn't throw a 200 line useless backtrace.</p>

  497. 

  498. <p>I am not joking. It will try to execute commands such as e.g.

  499. </p>

  500. 

  501. <blockquote>

  502. <tt>/bin/bash -c "wget http://www.scala-lang.org/files/archive/scala-2.10.3.deb ; dpkg -x ./scala-2.10.3.deb /"</tt>

  503. </blockquote>

  504. 

  505. <p>

  506. Note that it doesn't even <i>install</i> the package properly, but extracts

  507. it to your root directory. The download does not check any signature, not even

  508. SSL certificates. (Source:

  509. <a href="https://github.com/apache/bigtop/blob/master/bigtop_toolchain/manifests/scala.pp">Bigtop puppet manifests</a>)

  510. </p>

  511. 

  512. <p>Even if your build would work, it will involve Maven downloading

  513. unsigned binary code from the internet, and use that for building.</p>

  514. 

  515. <p>Instead of writing clean, modular architecture, everything these days

  516. morphs into a huge mess of interlocked dependencies. Last I checked, the

  517. Hadoop classpath was already over 100 jars. I bet it is now 150, without

  518. even using any of the HBaseGiraphFlumeCrunchPigHiveMahoutSolrSparkElasticsearch

  519. (or any other of the Apache chaos) mess yet.</p>

  520. 

  521. <p><b>Stack</b> is the new term for "I have no idea what I'm actually

  522. using".</p>

  523. 

  524. <p><b>Maven</b>, <b>ivy</b> and <b>sbt</b> are the go-to tools for having

  525. your system download unsigned binary data from the internet and run it on your

  526. computer.</p>

  527. 

  528. <p>And with containers, this mess gets even worse.</p>

  529. 

  530. <p>Ever tried to <b>security update</b> a container?</p>

  531. 

  532. <p>Essentially, the Docker approach boils down to downloading an

  533. unsigned binary, running it, and hoping it doesn't contain any backdoor

  534. into your companies network.</p>

  535. 

  536. <p>Feels like downloading Windows shareware in the 90s to me.</p>

  537. 

  538. <p>When will the first docker image appear which contains the Ask

  539. toolbar? The first internet worm spreading via flawed docker images?</p>

  540. 

  541. <p><hr/>

  542. <p>Back then, years ago, Linux distributions were trying to provide you

  543. with a safe operating system. With signed packages, built from a web of trust.

  544. Some even work on reproducible builds.</p>

  545. <p>But then, everything got Windows-ized. "Apps" were the rage, which you

  546. download and run, without being concerned about security, or the ability to

  547. upgrade the application to the next version. Because "you only live

  548. once".</p>

  549. <p><b>Update:</b> it was pointed out that this started way before Docker:

  550. « <em>Docker is the new '<tt>curl | sudo bash</tt>'</em> ». That's right,

  551. but it's now pretty much mainstream to download and run untrusted software

  552. in your "datacenter". That is bad, really bad. Before, admins would try hard

  553. to prevent security holes, now they call themselves "devops" and happily

  554. introduce them to the network themselves!</p></p>
