# Docker Compose
|
||
|
|
|
||
|
|
## Environment
|
||
|
|
|
||
|
|
Prepare an environment file following the example in [env/fqdn_context.env.example](env/fqdn_context.env.example):
|
||
|
|
```
|
||
|
|
CONTEXT=foodstuffs_hongkong
|
||
|
|
DOCKER_SUBNET=172.24.23.0/24
|
||
|
|
HAPROXY_VERSION=latest
|
||
|
|
```
|
||
|
|
|
||
|
|
Var `${DOCKER_SUBNET}` is optional and defaults to `${DOCKER_SUBNET-172.24.23.0/24}`. Treat `CONTEXT` as a team name, purpose or scope. If the same Docker application can run multiple times and serve different tenants then `CONTEXT` is what distinguishes one instance from the other. Here `foodstuffs_hongkong` indicates for example a Hong Kong-based foodstuffs team of some sort.
|
||
|
|
|
||
|
|
## Vars
|
||
|
|
|
||
|
|
Define Docker Compose variables, use the `COMPOSE_ENV_FILE` defined above in [Environment](#environment):
|
||
|
|
```
|
||
|
|
export COMPOSE_DIR='/opt/containers' # Or wherever this repo is checked out
|
||
|
|
export COMPOSE_FILE="${COMPOSE_DIR}"'/docker-compose.yml'
|
||
|
|
export COMPOSE_ENV_FILE=<add accordingly>
|
||
|
|
```
|
||
|
|
|
||
|
|
Run like so:
|
||
|
|
```
|
||
|
|
docker compose --file "${COMPOSE_FILE}" --env-file "${COMPOSE_ENV_FILE}" up --detach
|
||
|
|
```
|
||
|
|
|
||
|
|
Log entries will just be something along the lines of:
|
||
|
|
```
|
||
|
|
haproxy-CONTEXT | [NOTICE] (1) : New worker (8) forked
|
||
|
|
haproxy-CONTEXT | [NOTICE] (1) : Loading success.
|
||
|
|
```
|
