For information on debugging container issues, see Frequently Asked Questions
Here are different ways to help troubleshooting
--debug flag to any client command will give extra information
about internals. If there is no useful info, it can be added with the
logger.Debugf("Hello: %s", "Debug")
This command will monitor messages as they appear on remote server.
lxd server and running it in foreground with
flag will bring a lot of (hopefully) useful info:
systemctl stop lxd lxd.socket lxd --debug --group lxd ``` `--group lxd` is needed to grant access to unprivileged users in this group. ### REST API through local socket On server side the most easy way is to communicate with LXD through local socket. This command accesses `GET /1.0` and formats JSON into human readable form using [jq](https://stedolan.github.io/jq/tutorial/) utility: ```bash curl --unix-socket /var/lib/lxd/unix.socket lxd/1.0 | jq .
See the RESTful API for available API.
REST API through HTTPS
HTTPS connection to LXD requires valid
client certificate, generated in
lxc remote add. This certificate should be passed to
connection tools for authentication and encryption.
Examining certificate. In case you are curious:
openssl x509 -in client.crt -purpose
Among the lines you should see:
Certificate purposes: SSL client : Yes
with command line tools
wget --no-check-certificate https://127.0.0.1:8443/1.0 --certificate=$HOME/.config/lxc/client.crt --private-key=$HOME/.config/lxc/client.key -O - -q
Some browser plugins provide convenient interface to create, modify
and replay web requests. To authenticate againsg LXD server, convert
lxc client certificate into importable format and import it into
For example this produces
client.pfx in Windows-compatible format:
openssl pkcs12 -clcerts -inkey client.key -in client.crt -export -out client.pfx
After that, opening https://127.0.0.1:8443/1.0 should work as expected.
