Base Docker image from which almost all others are derived. It is not meant to be run on its own.
It's based off off Alpine Linux, and includes s6 overlay and confd.
Requires alpine:3.11.7
| Environment Variable | Default | Description |
|---|---|---|
| ETCD_HOST | etcd | The host where etcd, can be found |
| ETCD_HOST_PORT | 2379 | The port where etcd can be accessed |
| ETCD_CONNECTION_TIMEOUT | 0 | Timeout to wait for a connection to etcd |
If etcd cannot be reached the container will use environment variables as a
backend for confd. The timeout is set to 0 by default to ensure containers
start quickly in a development environment where etcd is not running.
Users do not require etcd to run the containers, environment variables can be used instead for simplicity.
