Services
Woodpecker provides a services section in the YAML file used for defining service containers. The below configuration composes database and cache containers.
Services are accessed using custom hostnames.
In the example below, the MySQL service is assigned the hostname database and is available at database:3306.
steps:
build:
image: golang
commands:
- go build
- go test
services:
database:
image: mysql
cache:
image: redis
Configuration
Service containers generally expose environment variables to customize service startup such as default usernames, passwords and ports. Please see the official image documentation to learn more.
services:
database:
image: mysql
+ environment:
+ - MYSQL_DATABASE=test
+ - MYSQL_ALLOW_EMPTY_PASSWORD=yes
cache:
image: redis
Detachment
Service and long running containers can also be included in the pipeline section of the configuration using the detach parameter without blocking other steps. This should be used when explicit control over startup order is required.
steps:
build:
image: golang
commands:
- go build
- go test
database:
image: redis
+ detach: true
test:
image: golang
commands:
- go test
Containers from detached steps will terminate when the pipeline ends.
Initialization
Service containers require time to initialize and begin to accept connections. If you are unable to connect to a service you may need to wait a few seconds or implement a backoff.
steps:
test:
image: golang
commands:
+ - sleep 15
- go get
- go test
services:
database:
image: mysql
Complete Pipeline Example
services:
database:
image: mysql
environment:
- MYSQL_DATABASE=test
- MYSQL_ROOT_PASSWORD=example
steps:
get-version:
image: ubuntu
commands:
- ( apt update && apt dist-upgrade -y && apt install -y mysql-client 2>&1 )> /dev/null
- sleep 30s # need to wait for mysql-server init
- echo 'SHOW VARIABLES LIKE "version"' | mysql -uroot -hdatabase test -pexample
