cloud init CentOS 6

[itvietnam]

Hello,

we are testing cloud init features on CentOS 6. Images downloaded from https://cloud.centos.org/centos/6/images/

Image name: CentOS-6-x86_64-GenericCloud.qcow2

We follow this guide: https://pve.proxmox.com/wiki/Cloud-Init_Support to create VM and add cloud-init image.

The test is ok for VM hostname, except following error:

• Username: created but can not login with provision password
• DNS: error
• networking: error
• SSH key injection: can not

May we know how to debug this problem?

 

[dcsapak]

please use a newer cloudinit version , old cloudinit versions are mostly broken

 

[itvietnam]

we install via yum, this version is 0.7.5, is this latest already?

 

[dcsapak]

the cloudinit versions shipped in the default repositories is broken on most distros, current cloud init is 18.4

you need newer one for Centos 7 I updated to 1.8.x all works good
they are dev packages though
I see there are some for 6

https://copr-be.cloud.fedoraproject.org/results/@cloud-init/cloud-init-dev/

maybe this will work for you

Centos 7 I updated to 1.8.x all works good

CentOS 7 is running ok.

We tested 12 templates, downloaded from cloud base image and half of them are errors.

Debian 9 also needs the newer one try the one from buster it works for me
wget http://ftp.us.debian.org/debian/pool/main/c/cloud-init/cloud-init_18.3-3_all.deb
apt-get install python3-jsonschema
dpkg -i cloud-init_18.3-3_all.deb



Not sure why you want to support the EOL editions and I have not tested because I don't want them but like dcsapak says they need to have newer cloud-int like 1.8.X

Thanks,

CentOS 6 is ok now, now i'm trying to fix the remaining version.

What do you mean EOL? CentOS 6 is still using publicly from many VPS provider such as DigitalOccean, Vultr, Linode. Debian 9 is not a EOL version.

 

[Craig St George]

sorry you are right
Full updates May 10th, 2017

We stopped support it some time ago so I was mistaken

all things work except disk resize did not work. We use cloud-init with modules for WHMCS provided by modulesgarden.
