I have followed the below steps for creating a custom rootfs image for booting with firecracker:-
https://github.com/firecracker-microvm/firecracker/blob/master/docs/rootfs-and-kernel-setup.md
Once the VM is up, it asks for the login username and password.
I have tried root/root just like the one provided in the hello-rootfs image provided in examples. But unable to login via the same credentials.
Do we need to add any other module / configuration apart from the steps mentioned in the doc for user login?
You can use chroot to set root password inside the container:
chroot /my-rootfs
passwd

I have installed gitlab server using docker compose but after the installation I am not getting a default screen where we create first Admin user. Instead of that it is asking me to enter username and password.
If I see this correctly, the gitlab_root_password should be set in the Compose file. This should then be used to log in for the first time.

I'm trying to create a user for ceph dashboard with admin role. Version is Nautilus 14.2.19 and deployed with manuel installation.
I've installed dashboard module, installed all dependencies and enabled it. My dashboard is reachable from the monitor ip and default port of 8443.
When I run te command:
ceph dashboard ac-user-create <user> <pw> administrator
I get the following error:
Please specify the file containing the password/secret with "-i" option.
After digging for information about this it says there must be a file in bcrypt format. Is there a default created file for this? Or if it's needed to create one how can I do it?
Nevermind, it seems you just need to create a text file and write your password in it.
When you run the command like this:
ceph dashboard ac-user-create <user> -i /file/location administrator
It creates the user and applies the password in an encrypted format.
I have a Public Cloud instance via OVH. I reinstalled my computer without backing up my ssh-key. I also forgot the root password for the server. I do have access to my Public Cloud control panel and rebooted with rescue mode.
However, when I change my root password (via the noVNC console) and then reboot to my Ubuntu disk, the new password is incorrect.
The passwd command returns: passwd: password updated successfully!.
But then I can't login as root with the new password after exiting rescue mode.
What am I doing wrong?:
By default, password login for root and the default user is not possible by ssh. If you used a key, you'll need to replace that key via the Rescue Mode. You can follow that guide to do that : Replacing your lost ssh key pair
Also, remember that you need to mount your partition containing your OS before doing any modification. The step are well describe in the OVH documentation here : Put an instance in Rescue Mode
When you are in rescue mode and you change the password with passwd, you change the password for the rescue mode only !
If you want to change you "normal OS" password from the rescue mode, you first need to chroot into the partition holding your "normal OS" and then use passwd there to change your password:
$ chroot /mnt/vdb1/
$ passwd

Following the documentation guide, I have booted up a master and slave and I can see it connected via the logs:
Boot up master
$ domain.sh --host-config=host-master.xml
Boot up slave
$ domain.sh --host-config=host-slave.xml
I've also followed the steps to set up the admin user via the add-user.sh. Further research indicated that I should use the add-user-keycloak.sh script to add an initial admin user:
./add-user-keycloak.sh -u john
Press ctrl-d (Unix) or ctrl-z (Windows) to exit
Password:
Added 'john' to '../standalone/configuration/keycloak-add-user.json', restart server to load user
Reran the master and slave, but cannot login to admin console.
However, what's interesting is when I tried to boot up in standalone mode I was able to the admin console as john:
./standalone.sh
Is this a bug or am I missing something (most likely) that's not in the documentation?
Thanks in advance...
Figured it out, hope this helps somebody.
Before you start in domain cluster mode:
./domain --host-config=host-master.xml
./domain --host-config=host-slave.xml
you must first create the admin so you can log in to admin console using the --sc tag, otherwise add-user-keycloak.sh only adds the admin user for the standalone mode. To do that:
./add-user-keycloak.sh --sc ../domain/servers/server-one/configuration -u john -p password
if configuration folder does not exist, then create the directory.
The ./add-user-keycloak.sh script seems to be a little outdated. Currently (as of Keycloak 12.0.2 version) it creates keycloak-add-user.json file in ./domain/configuration/ directory - That is wrong!
The file should be in ./domain/servers/server-one/configuration.
Now you just have to move the file to that directory, restart the server and it should work properly.
I found this solution on this 2-year old email thread:

I need to install a program in gcloud environment. When I ssh, however, I need to become root to use yum, but I never set a root password. Is there a default password set?
Also, I see different file systems when I login via ssh from commandline or using ssh button at the browser int the "Compute Engine" site.
