Considering the current working directory is where your docker-compose.yml
file is located:
docker run --rm -it --name dcv -v $(pwd):/input pmsipilot/docker-compose-viz render -m image docker-compose.yml
This will generate the docker-compose.png
file in the current working directory.
Before you start, make sure you have:
- Composer installed,
- PHP 7 installed,
- GraphViz installed (see below for a guide on how to install it)
git clone https://github.com/pmsipilot/docker-compose-viz.git
make vendor
# Or
composer install --prefer-dist
bin/dcv
- On MacOS:
brew install graphviz
- On Debian:
sudo apt-get install graphviz
Usage:
render [options] [--] [<input-file>]
Arguments:
input-file Path to a docker compose file [default: "./docker-compose.yml"]
Options:
--override=OVERRIDE Tag of the override file to use [default: "override"]
-o, --output-file=OUTPUT-FILE Path to a output file (Only for "dot" and "image" output format) [default: "./docker-compose.dot" or "./docker-compose.png"]
-m, --output-format=OUTPUT-FORMAT Output format (one of: "dot", "image", "display") [default: "display"]
--only=ONLY Display a graph only for a given services (multiple values allowed)
-f, --force Overwrites output file if it already exists
--no-volumes Do not display volumes
-r, --horizontal Display a horizontal graph
--ignore-override Ignore override file
Links (from services.<service>.links
) are displayed as plain arrows pointing to the service that declares the link:
If we look at the link between mysql
and ambassador
, it reads as follow: "mysql
is known as mysql
in ambassador
."
If we look at the link between ambassador
and logs
, it reads as follow: "ambassador
is known as logstash
in logs
."
External links are displayed using the same shapes but are grayed:
Volumes (from services.<service>.volumes_from
) are displayed as dashed arrows pointing to the service that uses the volumes:
If we look at the link between logs
and api
, it reads as follow: "api
uses volumes from logs
."
Volumes (from services.<service>.volumes
) are displayed as folders with the host directory as label and are linked to the service that uses them dashed arrows.
If we look at the link between ./api
and api
, it reads as follow: "the host directory ./api
is mounted as a read-write folder on /src
in api
." Bidirectional arrows mean the directory is writable from the container.
If we look at the link between ./etc/api/php-fpm.d
and api
, it reads as follow: "the host directory ./etc/api/php-fpm.d
is mounted as a read-only folder on /usr/local/etc/php-fpm.d
in api
." Unidirectional arrows mean the directory is not writable from the container.
Dependencies (from services.<service>.depends_on
) are displayed as dotted arrows pointing to the service that declares the dependencies:
If we look at the link between mysql
and logs
, it reads as follow: "mysql
depends on logs
."
Ports (from services.<service>.ports
) are displayed as circle and are linked to containers using plain arrows pointing to the service that declares the ports:
If we look at the link between port 2480
and orientdb
, it reads as follow: "traffic coming to host port 2480
will be routed to port 2480
of orientdb
."
If we look at the link between port 2580
and elk
, it reads as follow: "traffix coming to host port 2580
will be routed to port 80
of elk
."
Extended services (from services.<service>.extends
) are displayed as components (just like normal services). The links between them and the extending services are
displayed as inverted arrows:
If we look at the link between mysql
and db
, it reads as follow: "mysql
extends service db
".
Networks (from networks.<network>
) are displayed as pentagons. The links between them and services are displayed as plain arrows pointing to the network:
If we look at the link between mysql
and the global
network, it reads as follow: "mysql
is known as mysql
, db
and reldb
in the global
network.
The legacy
network is an external so it's displayed as a grayed pentagone.
