Hoster

A simple "etc/hosts" file injection tool to resolve names of local Docker containers on the host.

hoster is intended to run in a Docker container:

docker stop docker-hoster
docker rm docker-hoster
docker run --name docker-hoster --restart=unless-stopped -d -v /var/run/docker.sock:/tmp/docker.sock -v /etc/hosts:/tmp/hosts thisisdevelopment/docker-hoster

The docker.sock is mounted to allow hoster to listen for Docker events and automatically register containers IP.

Hoster inserts into the host's /etc/hosts file an entry per running container and keeps the file updated with any started/stoped container.

Container Registration

Hoster provides by default the entries

<hostname>.<domainname> (or <hostname>.hosts.docker if no domainname is present)
<service>.<project>.services.docker
<container name>.containers.docker (if no service/project name are found)
<alias> for each network alias

Containers are automatically registered when they start, and removed when they die.
