| kruster95 | hi all | 12:55 |
|---|---|---|
| kruster95 | i want to use cloud-init and terraform to configure my virtual server (vmware), i am looking for some documentation, if you can give me a hand. thank you | 12:57 |
| minimal | kruster95: well basically you either need a pre-existing VM image that has cloud-init enabled or you need to build a VM yourself. The VMware DataSource changed/a new one was added recently so not sure if any official Linux distro cloud images have the new DataSource yet. Which distro are you using? | 13:04 |
| minimal | Once you have a suitable VM image then when you create a VM using terraform you supply the user-data as part of the terraform action | 13:05 |
| kruster95 | minimal : I have my rhel8 template with cloud-init to install | 13:13 |
| minimal | so have you actually tried creating a VM using terraform and passing user-data to it? | 13:13 |
| kruster95 | and my block in terraform : extra_config = { | 13:13 |
| kruster95 | "guestinfo.metadata" = base64encode(file("${path.module}/templates/metadata.yaml")) | 13:13 |
| kruster95 | "guestinfo.metadata.encoding" = "base64" | 13:13 |
| kruster95 | "guestinfo.userdata" = base64encode(file("${path.module}/templates/userdata.yaml")) | 13:13 |
| kruster95 | "guestinfo.userdata.encoding" = "base64" | 13:13 |
| kruster95 | } | 13:13 |
| kruster95 | nothing happens | 13:14 |
| minimal | and did you log into the created VM and look at /var/log/cloud-init.log to see what happened? | 13:14 |
| kruster95 | I have nothing special in the logs | 13:15 |
| minimal | nothing special? did it setup network config based on the VMware DataSource? | 13:16 |
| minimal | did it see the user-data and act upon any of it? | 13:16 |
| kruster95 | the network is correctly configured | 13:21 |
| kruster95 | how does my vm interact with terraform? | 13:22 |
| minimal | kruster95: and the DataSource that the logs indicate was used? | 13:22 |
| kruster95 | on my template, I have not configured a datasource | 13:23 |
| kruster95 | I just installed cloud-init | 13:23 |
| minimal | your VM does not interact with Terraform, Terraform is used to create the VM via which hypervisor (VMware in this case) is used and it passes the cloud-init metadata and network config and user-data to the hypervisor to pass on (in some way) to the VM's cloud-init | 13:23 |
| minimal | In the /var/log/cloud-init.log it will indicate which DataSource was used during boot | 13:24 |
| kruster95 | "DataSourceOVF.py[DEBUG]: VMware Virtualization Platform found" | 13:25 |
| kruster95 | I can see the network configuration in the logs | 13:26 |
| minimal | ok, so it used the OVF datasource | 13:27 |
| minimal | so is there any reference to user-data in the logfile? | 13:27 |
| kruster95 | no precisely, i think i have a config problem in terraform. | 13:30 |
| minimal | You probably should read https://cloudinit.readthedocs.io/en/latest/topics/datasources/ovf.html | 13:30 |
| minimal | there are notes there about VMware specific config settings | 13:30 |
| minimal | why focus on terraform as the likely problem? I suspect it is either the cloud-init settings for the OVF DataSource or the VMware configuration | 13:31 |
| kruster95 | because my custo is in terraform | 13:32 |
| minimal | custo? | 13:32 |
| kruster95 | customization | 13:33 |
| kruster95 | create users | 13:33 |
| kruster95 | install package | 13:33 |
| minimal | terraform simplly passes this to VMware | 13:34 |
| minimal | in the OVF document I referenced did you read this? "On VMware platforms, VMTools use is required for OVF datasource configuration settings as well as vCloud and vSphere admin configuration." | 13:34 |
| minimal | have you setup VMTools? | 13:34 |
| kruster95 | yes it is correctly configured | 13:38 |
| minimal | I'm not familiar with VMware, so are there some logs where you can check if (a) VMware received the user-data from Terraform and (b) if VMware supplied the user-data to cloud-init? | 13:40 |
| minimal | kruster95: in cloud-init code for OVF DS I see this comment: "When the VM is powered on, the "VMware Tools" daemon copies the customization specification file to /var/run/vmware-imc directory. cloud-init code needs to search for the file in that directory which indicates that required metadata and userdata files are now present." | 13:56 |
| minimal | so does /var/run/vmware-imc directory exist on the booted VM and does it contain anything? | 13:56 |
| Paul | hello, was trying to determine which stage OVF data is actually read in, my suspicion is that it is read in the local stage, but I can't seem to find that documented. Does anyone know if this is true and where it might be documented? | 21:26 |
| === Paul is now known as Paul88 | ||
| Paul88 | yea, think i confirmed it, it checks for the OVF data between starting "init-local" (cloud-init-local.service), and when it says it is starting "init" (cloud-init.service) in the logs. | 22:07 |
| rharper | Paul88: it's not clearly documented, in the context of cloud init, in code, seeing the sources.DEP_FILESYSTEM indicates that it runs as soon as cloud-init init --local runs and searches for datasources that are detectable without networking, https://github.com/canonical/cloud-init/blob/main/cloudinit/sources/DataSourceOVF.py#L710 | 22:13 |
| Paul88 | Thank you Ryan | 22:13 |
