Unable to make dataplaneapi listen on unix socket

[odivlad]

Hi,

I want dataplaneapi to run and listen on unix socket with socket_path option, but I'm unable to.
Running as root dataplaneapi manually with next config:

config_version: 2
dataplaneapi:
  socket_path: /var/run/dataplaneapi.sock
  debug_socket_path: /var/run/dataplaneapi_debug.sock
  pid_file: /var/run/dataplaneapi.pid
  userlist:
    userlist: dataplaneapi
  transaction:
    transaction_dir: /etc/dataplaneapi/transactions
  resources:
    maps_dir: /etc/dataplaneapi/maps
    ssl_certs_dir: /etc/dataplaneapi/hssl
    general_storage_dir: /etc/dataplaneapi/general
    spoe_dir: /etc/dataplaneapi/spoe
haproxy:
  config_file: /etc/haproxy/haproxy.cfg
  reload:
    service_name: haproxy
    reload_strategy: systemd

, I get next:

# dataplaneapi -f dataplaneapi.yml --log-level debug
time="2024-03-01T21:22:10+03:00" level=info msg="Build from: https://github.com/haproxytech/dataplaneapi"

time="2024-03-01T21:22:11+03:00" level=info msg="-- command socket Starting on /var/run/dataplaneapi_debug.sock"

There is no such file /var/run/dataplaneapi.sock:

# ls -l /var/run/dataplaneapi*
srwxr-xr-x 1 root root 0 Mar  1 21:22 /var/run/dataplaneapi_debug.sock
-rw-r--r-- 1 root root 7 Mar  1 21:22 /var/run/dataplaneapi.pid

Running with strace I see no attempts to bing on unix socket, though the option is processed and written in re-generated dataplaneapi.yml config file.

My version is 2.9.0.

What am I doing wrong?
Thanks in advance.

Were you able to solve this issue? Currently having same problem.

Nope. Using tcp socket.

Can you elaborate more on the solution?
