LXDMosaic: Web GUI

LXD

Yeah thats the way, the only other option was deploy a pyhton script that gathered the data and wrote it to a file and the use the file api to pull the files from the file system (this is messy in practice though and much harder to code for (it also grows the instances filesystem which isn’t great))

Also you have to understand its pretty useless unless the user has LXCFS enabled on the hosts, other wise all instances will report the same load average

Hi @turtle0x1

Keep up the good work!

I built LXD cluster on some physical machine, all using Ubuntu Server 20.04… I have LXDmosaic installed via Snap in one of my LXD instance… Feeling good to have a GUI instead of CLI for seasonal sysadmin like me…

I think this project is very potential!

Looking forward for future improvements… By the way, just an input, maybe in the future it will have change skin/theme feature…

Thanks!

Its because you used user/User instead of Users - I see the docs are wrong tracking here

So it should be;

update `Users` set `User_Password` = “$2y$10$gDLdVHx2DEuoB81DobEcnFIGScRjFg6hoN/kDmvJfn6SmMP0OW2” where User_ID = 1;

After login I am going to add server then given admin with password. but when I have click on
Launch LXD mosaic it shows “Cant run first run /var/www/LxdMosaic/src/classes/Tools/InstanceSettings/FirstRun.php 31”

45

Set the admin password to NULL and you will be able to run first run again.

Because you have no servers it wants you to run first run, the admin password should not be set when first run is run - this prevents people abusing “first run”. If you have deleted all the hosts you need to set the admin password back to NULL.

46

how can I set it nul?

47 
update `Users` set `User_Password` = NULL where User_ID = 1;

Please can you open an issue on Github instead of continuing to comment here if this doesn’t work, this really just a release thread! I was wrong its;

update `Users` set`User_Password` = '' where User_ID = 1;

@turtle0x1 why the snap lxdmosaic has no aarch64 support?

51

cause i have no aarch64 to test snap on (all my RPI’s are to old which is just ridiculous)

You can install using the container method instead, shouldn’t have any problems (from memory)

Change Highlights

  • One socket per user for all hosts “operations” information, drastically reducing browser weirdness
