I can't install plugins elasticsearch in docker

Elastic Stack Elasticsearch

I'm trying to install a plugin for elasticsearch in a docker container. I run the command:

docker exec a15de2d3dc21 bin/elasticsearch-plugin install analysis-phonetic

and get an error:

-> Installing analysis-phonetic
-> Failed installing analysis-phonetic
-> Rolling back analysis-phonetic
-> Rolled back analysis-phonetic

I am using this docker image
docker.elastic.co/elasticsearch/elasticsearch:7.17.2

and it worked a couple of days ago. Could you tell me the reason?

The problem was resolved by restarting the Docker service. Perhaps it will be useful to someone.
