Now obviously you could do what for example Java does with a jar file,<br>

I'm aware that packaging it in rpm/deb would be extremely difficult and there are plenty more examples of this. But, putting it in a container wouldn't make my life any easier and would, in fact, just add yet another layer of something to keep up to date. For some things a pragmatic approach of treating it as a standalone entity loosely linked to the OS is warranted. But at that point I'm faced with doing with N amount of effort where N = "amount of effort to install software" or N + C where C = "work out containerizing and extra step of pulling container when running". N + C > N for any controlled OS environment like a cluster or, one would hope, production environments which handle my credit card and private data. In my view it follows then that one would only choose to do the N + C effort if one had extra warm bodies around that </div><div>needed tasks. </div><div><br></div><div>I might also consider it from this perspective. I pull plugins into my vim config without ever entertaining the thought that they should have been packaged as rpms/debs. Maybe some software just doesn't deserve to be packaged? Either because it already has a means of distribution in userspace (plugins, pip, npm, cran,...) or because it's just crap software. I accept that containers may be the best way to deal with crap, as previously noted.</div><div><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><br>
Option 2 worked 20 years ago when we only cared about 2 or 3<br>
distributions of Linux and had a lot less open source / free software.<br>
But, unfortunately, it does not scale and so for that reason (and a<br>
few others) the effort to create Docker / npm, maven, etc. is the<br>
lesser of the options.<br>
<br></blockquote><div><br></div><div>I think the more accurate phrase there is "lesser of the evils". Every time I get into a discussion about this topic it feels as if the discussion is about determining which rusty saw is the best choice to saw off my own leg and when I suggest "maybe we shouldn't saw off our own legs?" I'm met with a chorus of "but griznog, EVERYONE is sawing of their own leg with X, Y and Z these days!! You simply must attend the next Leg Sawing Conference..." Electron and nodejs is a great example. No one seems to step back and consider that perhaps the entire concept is broken and maybe wasn't a good idea. But unfortunately it's quite easy to blame the packaging tools and at this point many careers and reputations are intertwined with nodejs continuing to be popular, so the people in the best position to consider it was a bad idea are unlikely to consider that.</div><div><br></div><div>In my view containers are little more than incredibly complex static binaries and I've already sat through years and years of discussions about the problems of static binaries and concluded they are great for a few narrow cases but not the best solution in general. So, 'cat every_argument_against_static_binaries_ever | sed s/static binary/container/g'. That containers require some minimal amount of setuid root or a daemon to wrap root access adds a significant bit of weight to those criticisms. </div><div><br></div><div>I realize I'm the odd person out here and that containers are a part of the fabric now, for better or worse. In the same way I'm forever stuck dealing with the clusterfsck that Java is, I'll be stuck with containers. To that end massive kudos to singularity for at least bringing some semblance of sanity to the mix. FWIW, I think containers are better than Java, but I will still grumble as I slowly begin dragging the rusty blade back and forth across my thigh. </div><div><br></div><div>griznog</div></div></div>
