How can I send a restart signal from one container to another?

Question

linux

Good afternoon. It is necessary to raise a container with CertBot on the host and configure automatic reissue of certificates for other containers. I'm going to use a common volume for this, where certbot will generate certificates, and other containers will take them. But after the container picks up the certificate, I need to restart it. Can this be done from a container with certbot without using docker socket? What are the options for solving this problem?

Answer 1

No need to take the certificates issued by certbot anywhere. To restart, it is enough to register the certificate verification in the entrypoint.
