The command line supports the following options: All interactions with the MockServer are logged including setting up expectations, matching expectations, clearing expectations and verifying requests. As @MichaelNeale noticed, there is no sense to use this method in Dockerfile (except when we need this IP during build time only), because this IP will be hardcoded during build time. The reason is security that is set in place by docker that by default is banning communication from a container towards the host or other containers running on your host. The easiest way to get it is via ifconfig (interface docker0) from the host: From inside a docker, the following command from a docker: ip -4 route show default | cut -d" " -f3.

By default, this container uses SQLite for data storage but the Nextcloud setup wizard (appears on first run) allows connecting to an existing MySQL/MariaDB or PostgreSQL database.

The .env file sets environment variables that are used when you run the Elastic Stack security features require TLS encryption for the transport networking If the tarball defines a repository, the tarball should also include a repositories file at your Docker container. To ensure that Docker for Desktop exposes MockServer update the service type to LoadBalancer using --set service.type=LoadBalancer and set the exposed port using --set service.port=1080, as follows: MockServer will then be reachable on http://localhost:1080. These values are shown only when you start Elasticsearch for the first time. Therefore, it is recommended to first create a user defined bridge network and attach the containers to that network. Today, I have needed this, and found 2 very simple ways: use ipconfig or ifconfig on your host and make note of all IP addresses. Same as above but use docker.for.mac.host.internal instead. base64-encoded JSON object containing some filesystem header information about Note: It is also possible to specify a SNAPSHOT version to get the latest unreleased changes.
