Deploy to Production • Set DOCKER_HOST • Use -H or --host options with Docker commands • Use a Docker Context

Slide 130

Slide 130 text

Deploy to Production DOCKER_HOST=ssh: / / webdevwithmatt@ docker compose up export DOCKER_HOST=ssh: // webdevwithmatt@ && \ docker compose up docker -H ssh: // webdevwithmatt@ compose up docker - - host ssh: / / webdevwithmatt@ compose up

source: https://docs.docker.com/engine/context/working-with-contexts/ A single Docker CLI can have multiple contexts. Each context contains all of the endpoint and security information required to manage a different cluster or node. The docker context command makes it easy to configure these contexts and switch between them.

Slide 132

Slide 132 text

Docker Contexts • Create a context • Set it as the default context • Run Docker commands

Slide 133

Docker Contexts docker context create remote \ -docker "host=ssh: / / deploy@" docker context use remote
