docker - 启用 Docker 远程 API - raspberry pi/raspbian

Question

我的出发点是:

• How to use docker remote api to create container? ,

所以我编辑 /etc/init/docker.conf 并将 DOCKER_OPTS 变量的 2 次出现更新为:

DOCKER_OPTS='-H tcp://0.0.0.0:4243 -H unix:///var/run/docker.sock'

然后，列出 docker 图像的简单测试失败:

$ service docker restart
$ curl -X GET http://10.143.0.218:4243/images/json
curl: (7) Failed to connect to 10.143.0.218 port 4243: Connection refused

Docker 版本是:

$ sudo docker version

 API version:  1.24
 Go version:   go1.6.3
 Git commit:   6b644ec

[08/18/2016 at 6:00 am] Oliver Weise says: Thanks, that put me in the right direction. However since Ubuntu 16.04 with its systemd docker daemon the /etc/default/docker is no longer effective. Instead you need to create a systemd dropin file.

I placed such a file under: /etc/systemd/system/docker.service.d/remote-api.conf

With the contents:

[Service]
ExecStart=
ExecStart=/usr/bin/dockerd -H tcp://127.0.0.1:2376 -H unix:///var/run/docker.sock

(Yes, the double ExecStart is necessary)

After that run:

sudo systemctl daemon-reload // reloading daemon definitions
sudo systemctl restart docker
