For the past week I worked on getting a Ironic standalone to run on an Ampere AltraMax server in our lab. As I recently was able to get a baremetal node to boot, I wanted to record the steps I went through.
Continue readingI have to pull the log out of a docker process to figure out why it is crashing. The Docker container name is ironic_ipxe.
cat $( docker inspect ironic_ipxe | jq -r '.[] | .LogPath' ) |
The code that Rich M gave me a while back has bit rotted. At some point, I need to get an updated version, but until then, I can continue to talk to the FreeIPA server using Python and the Requests library. In the future, I can get a session cookie, but for now, python3-request-gssapi will work to authenticate me, provided I have a valid TGT.
I pulled the requests-gssapi library from Koji, as it does not currently ship in any of the RHEL8 repos. Here is the one I installed.

Note that this quick-and-dirty code runs on the IPA server itself. A better approach would be to read the Server name out of /etc/ipa/default.conf.
#!/bin/python3 import requests from requests_gssapi import HTTPSPNEGOAuth import socket hostname = socket.gethostname() url = "https://%s/ipa/json" % hostname referer = "https://%s/ipa" % hostname body = {"method":"user_find","params":[[""],{}],"id":0} r = requests.post(url, json = body, auth=HTTPSPNEGOAuth(), headers = { 'Content-Type': 'application/json', 'Accept': 'applicaton/json', 'referer': referer}) print(r.status_code) if r.status_code == 200: print(r.text) |
The JSON file format is used for marshalling data in lots of different applications. If you are new to an application, and don’t know the data, it might be hard to visually parse the JSON and understand what you are seeing. The jq command line utility can help make it easier to scope in to a section of the file. This is a starting point.
