Likely root cause: java.nio.file.FileSystemException: /usr/share/elasticsearch/data/nodes/0: Not a directory

I don't know why this mistake happened.
Read a lot of posts on the internet, rarely find the same mistakes as me.
Because I just started learning to use this, but the simple first step can not run.
This is the command I click to run on the docker.

docker run -d \
	--name es \
    -e "ES_JAVA_OPTS=-Xms512m -Xmx512m" \
    -e "discovery.type=single-node" \
    -v es-data:/usr/share/elasticsearch/data \
    -v es-plugins:/usr/share/elasticsearch/plugins \
    --privileged \
    --network es-net \
    -p 9200:9200 \
    -p 9300:9300 \
elasticsearch:7.12.1

This is his run error

uncaught exception in thread [main]

Welcome.

What does your local es-data dir is looking like?

BTW use the latest 7.17 version.

This means you've upgraded this node to 8.x and then tried to downgrade it again, which won't work. Run cat /usr/share/elasticsearch/data/nodes to see more details.
