package main import ( "fmt" "github.com/docker/docker/engine/job" ) func main() { envVar := "PORT" defaultValue := 8080 portValue := job.GetenvInt(envVar, defaultValue) fmt.Printf("Port Value: %d", portValue) }
package main import ( "fmt" "github.com/docker/docker/engine/job" ) func main() { envVar := "MAX_CONNECTIONS" defaultValue := 1000 connectionsValue := job.GetenvInt(envVar, defaultValue) if connectionsValue > 500 { fmt.Println("Warning: Too many connections") } }This example demonstrates how to use the GetenvInt function to retrieve the value of an environment variable named "MAX_CONNECTIONS" as an integer. If the value is greater than 500, a warning is printed to the console. In both examples, the package library used is github.com/docker/docker/engine/job.
