例如:查询正在运行的容器列表,HTTP 方式以下:java
$ curl --unix-socket /var/run/docker.sock http:/v1.24/containers/json [{ "Id":"ae63e8b89a26f01f6b4b2c9a7817c31a1b6196acf560f66586fbc8809ffcd772", "Names":["/tender_wing"], "Image":"bfirsh/reticulate-splines", ... }]
在本机执行以下命令git
curl -v --unix-socket /var/run/docker.sock http:/v1.24/containers/json
一、引入 UnixSocket 工具包github
<dependency> <groupId>com.github.jnr</groupId> <artifactId>jnr-unixsocket</artifactId> <version>0.18</version> </dependency>
二、测试代码docker
public static void main(String[] args) { // 创建 Unix Socket 链接 File sockFile = new File("/var/run/docker.sock"); UnixSocketAddress address = new UnixSocketAddress(sockFile); UnixSocketChannel channel = UnixSocketChannel.open(address); UnixSocket unixSocket = new UnixSocket(channel); // 调用 Docker API PrintWriter w = new PrintWriter(unixSocket.getOutputStream()); w.println("GET /v1.24/containers/json HTTP/1.1"); w.println("Host: http"); w.println("Accept: */*"); w.println(""); w.flush(); // 关闭 Output,不然会致使下面的 read 操做一直阻塞 unixSocket.shutdownOutput(); // 获取返回结果 System.out.println("---- Docker Response ----"); BufferedReader br = new BufferedReader(new InputStreamReader(unixSocket.getInputStream())); String line; while ((line = br.readLine()) != null){ System.out.println(line); } unixSocket.close(); }
