环境配置是由Go第三方库viper来实现的。当程序启动时，viper会去读取`yaml`配置文件，以及将环境变量与配置文件中的变量对应起来。
|
||
|
||
以下是`yaml`配置文件，其中的变量可以被以`CRAWLAB_`为前缀的环境变量所覆盖。
|
||
|
||
```yaml
|
||
api:
|
||
address: "localhost:8000"
|
||
mongo:
|
||
host: localhost
|
||
port: 27017
|
||
db: crawlab_test
|
||
username: ""
|
||
password: ""
|
||
authSource: "admin"
|
||
redis:
|
||
address: localhost
|
||
password: ""
|
||
database: 1
|
||
port: 6379
|
||
log:
|
||
level: info
|
||
path: "/var/logs/crawlab"
|
||
isDeletePeriodically: "Y"
|
||
deleteFrequency: "@hourly"
|
||
server:
|
||
host: 0.0.0.0
|
||
port: 8000
|
||
master: "N"
|
||
secret: "crawlab"
|
||
register:
|
||
# mac地址 或者 ip地址，如果是ip，则需要手动指定IP
|
||
type: "mac"
|
||
ip: ""
|
||
spider:
|
||
path: "/app/spiders"
|
||
task:
|
||
