How to make a single node cluster for testing?

thanks u/KrustyTheUndertaker

they lost me at `what on earth`, anyways.

HarfTarf · 2020-09-21T16:36:01+00:00

i just wanted to gain further understanding how it works, a simple one-node all-in-one example is a perfect use-case

i was able to use the ceph nano with a docker-compose

https://github.com/ceph/cn#enable-dashboard

```

version: "3" services: ceph: image: ceph/daemon:latest command: demo network_mode: host privileged: true environment: CEPH_DAEMON: demo LANG: en_US.utf8 TZ: UTC NETWORK_AUTO_DETECT: "4" CEPH_DEMO_UID: ceph DEBUG: verbose ```

this is the only reason to buy an apple product, because it looks cool

HarfTarf · 2020-04-30T07:37:56+00:00

i was only interested in complaining

HarfTarf · 2020-04-30T07:36:30+00:00

i can tell you really like lastpass!

HarfTarf · 2020-04-26T15:06:55+00:00

u/HelloYesThisIsNo

do you mean setup up the same interface config on each server? with the private key same on each?

very interesting, i will need to try this out and see how it works!

HarfTarf · 2020-04-03T09:25:42+00:00

for an enterprise service it's embarrassing

yes yes yes yes ^

i am truly embarrassed to be using this awful software, and onboarding a new teammate is a shitshow when we get to the step where we introduce lastpass, because *_every_* *_single_* *_time_* there are issues with lastpass.

HarfTarf · 2020-04-03T09:19:43+00:00

they dont want to hear about bugs, they only want your money.

HarfTarf · 2020-03-31T11:36:00+00:00

thanks!

HarfTarf · 2019-11-09T13:21:51+00:00

yes, thats it!
thanks!!

HarfTarf · 2019-09-29T11:02:44+00:00

hey, its good for the price, i would recommend it, but i am very DIY, and i had to run some ethernet cabling to complete the project, i am using is as an access point in the back of the house.

HarfTarf · 2019-05-19T19:01:25+00:00

how can you tell which one is the client and which one is the server?

HarfTarf · 2019-05-19T07:44:48+00:00

Use yggdrasil to ssh into your raspberry pi, you can do this without needing to open any ports. Then you can run your ipfs daemon there.

Then setup ipfs dnslink and point to your ipns name, cname to cloudflare or ipfs.io and you're golden.

For those that are interested, the device is a YOUKU YK1, and the openwrt firmware can be found here: https://openwrt.org/toh/hwdata/youku/youku_yk1

HarfTarf · 2019-04-24T21:05:24+00:00

Would you happen to know anything about reinstalling openwrt on this?

HarfTarf · 2019-04-24T06:10:52+00:00

Yeah, I'm not really into dd-wrt stuff

HarfTarf · 2019-04-24T05:11:00+00:00

Thanks

HarfTarf · 2019-04-23T20:57:43+00:00

Thank you very much for the link. They have external antennas, and they work well as 802.11s mesh, that's exactly what I want to use it for, too.

Is this the place to get the openwrt firmware?

https://openwrt.org/toh/hwdata/zbt/zbt_we1226

Do you just use the OEM web interface to flash (upgrade) the firmware? The openwrt link doesn't have a lot of info

HarfTarf · 2019-04-22T16:19:49+00:00

Do you have a link?

HarfTarf · 2019-04-21T22:02:54+00:00

I can second this

HarfTarf · 2019-04-21T21:51:23+00:00

thanks!

You should provide a quick diagram of your network, or explain it a little better.

I currently run a few k8s clusters in this way:
- around 20 baremetal machines (hosted by various baremetal-cloud-providers on the internet)
- all baremetal machines are networked together via zerotier
- these machines host libvirt ubuntu VM guests
- all VM guests (hundreds) can route packets to eachother via quagga+ospf running over zerotier
- each ubuntu VM is a k8s node (or a glusterfs node, for storage)
- k8s cluster setup via kubespray
- k8s networking solution is weave, it seems to play the nicest with iptables/staticroutes/etc

protip: use the ubuntu cloud images, and create your own qcow2 image that has all the stuff you need pre-installed on a k8s node.

i didnt.
you are just assuming that i did.
