Rather than tell the docker daemon to not validate a self-signed certificate by using -insecure-registry, the better practice is to tell it to trust the self-signed certificate explicitly.ĭocker provides documentation which describes using openssl to generate a CA and server self-signed certificates. How To Generate a Self-Signed Certificate That Can Be Trusted By Docker Daemon Sonatype cannot recommend using the Docker -insecure-registry flag due to poorly defined semantics. However, the -insecure-registry flag has many unwanted side effects and can lead to obscure errors that would not be encountered otherwise. By marking the Nexus hostname and port as insecure, the docker daemon does not validate the trustworthiness of the secure connection. The intent is to avoid errors that would normally occur when using an untrusted certificate. To work around the Docker Daemon considering the Nexus HTTPS as untrustworthy, the daemon has an option called -insecure-registry . Nexus 3 is not configured with HTTPS connectors by default as configuring it requires an SSL certificate to be generated and configured manually.įor testing purposes, it is common that an administrator may want to use a self-signed TLS certificate for Nexus HTTPS connectors.Īlthough self-signed certificates can encrypt HTTP communication and be generated quickly, they are generally considered untrustworthy because the certificate identity has not been signed/verified by a third party certificate authority (CA). In order to use authentication, the Docker Daemon implementation enforces that the registry connection uses HTTPS. A private Docker registry such as Nexus Repository Manager 3 will require authentication from your users in order to publish docker images.
