In cases where there is high latency (ie, not-local network) `waitExitOrRemoved` was not receiving events for short-lived containers. This caused the client to hang while waiting for a notification that the container has stopped. This happens because `client.Events()` returns immediately and spins a goroutine up to process events. The problem here is it returns before the request to the events endpoint is even made. Even without high-latency issues, there is no guarantee that the goroutine is even scheduled by the time the function returns. Signed-off-by: Brian Goff <cpuguy83@gmail.com>
Go client for the Docker Engine API
The docker command uses this package to communicate with the daemon. It can also be used by your own Go applications to do anything the command-line interface does – running containers, pulling images, managing swarms, etc.
For example, to list running containers (the equivalent of docker ps):
package main
import (
"context"
"fmt"
"github.com/docker/docker/api/types"
"github.com/docker/docker/client"
)
func main() {
cli, err := client.NewEnvClient()
if err != nil {
panic(err)
}
containers, err := cli.ContainerList(context.Background(), types.ContainerListOptions{})
if err != nil {
panic(err)
}
for _, container := range containers {
fmt.Printf("%s %s\n", container.ID[:10], container.Image)
}
}
