Docker installed in wsl2 without docker desktop not starting with sudo service docker start

Question

After installing docker in wsl2 without docker desktop, and using sudo service docker start, we receive a success message, as shown below:

 sudo service docker start
 * Starting Docker: docker                                       [ OK ]

But when we run dockerd manually with sudo dockerd, we can find our error, as shown below:

ERRO[2022-08-30T09:32:39.000282429-04:00] failed to initialize a tracing processor "otlp"  error="no OpenTelemetry endpoint: skip plugin"

Answer 1

To solve this issue, we need to append in /etc/default/docker (ubuntu):

DOCKER_OPTS="--iptables=false"

or

run dockerd as shown below:

sudo dockerd --iptables=false
