How the fuck can someone say he's a "senior" sre, admin sys if he doesn't fucking know how to sign a docker image or even which docker image repository he uses!!!! How the fuck!!!! Now you just copy/paste a freaking co config and you're a sre?!?! He doesn't even know the difference between choreography and orchestration!!!!

Fuck!!!

Sysadminning is wide! I'd consider myself a medior sysadmin but my docker knowledge is bad. I know several seniors who have never worked with docker at all.

And as for the terms, I still learn new stuff every day :)

Not all systems run on docker 🤷‍♂️

unless it's his actual job to manage docker containers?

Yeah, but if you put on your resume that you are a Site reliability engineering (SRE), you must.

AdminSys != SRE

@jotamontecino That title does not define the technologies the company/you work with...

@jotamontecino For example, at my previous job, all sysadmins and supporters would fall outside your definition of a sysadmin.

Nobody knew docker, everyone knew KVM! And yes, they were (are) good engineers.

I am a Site Reliability Engineer and I have never needed to interact with docker at work. We do have a few docker containers, but I've never needed to touch them. 90% of our environment is either regular VMs or serverless.

It doesn't mean I don't know about docker; I know a little bit. But I don't know the answer to any of the questions you posed in your OP and I've never needed to.

First, if you're a senior SRE and don't know what orchestration or choreography means, there is a special place in devHell for you, near to the senior dev who don't know what a thread is or why chmod 777 is a big no-no.

Next, as I said he doesn't know the docker repository HE uses.
If you use some faas, cool I'll ask about it, if you're on a VM env, that's also cool I'll ask questions about it.

But no knowing your own fucking system is a big no-no for a senior!

"Senior" doesn't mean anything these days - that's the issue. In some places it's reserved for legitimate masters of their craft, in other places it's a title handed out at random to try to persuade people to stay without getting a salary increase.

So do you know how to pgp sign your email?
Manage DNS servers and fix DNSSEC for them?
Manage a ceph cluster?
Keep hundreds of computers and servers up to date?
Keep your IPS/IDS up to date?
Manage a email server?

Probably not,

What a retarded rant

@jotamontecino Man, I've been going at this with all respect but this is just bullshit.

Just because someone doesn't know what choreography means in the sysadmin world (I have no fucking clue), doesn't mean they can't be good at what they do.

Someone can be a VMware ninja and know nothing about KVM/Kubernetes and you name it and still be an awesome sysadmin.
Someone can be awesome at KVM and not know a single thing about kubernetes/VMware (this is me mostly, for the record) and be awesome at their job.
Someone can be a docker master and know zero about any other virtualization but be a great sysadmin regardless....

@linuxxx

Totally agree.

So, @jotamontecino - since you like docker , can you set up and manage a K8S cluster from scratch and keep it up to date?

I dont talk about a Raspberry Pi cluster, but a productioncluster with real hardware and that is going to be used by hundreds of different people and companies?
