Brief introduction 8 9 - The Remote API has replaced `rcli`. 10 - The daemon listens on `unix:///var/run/docker.sock` but you can bind 11 Docker to another host/port or a Unix socket. 12 - The API tends to be REST, but for some complex commands, like `attach` 13 or `pull`, the HTTP connection is hijacked to transport `STDOUT`, `STDIN` 14 and `STDERR`. 15 16 # 2.

It also contain the size of the 548 associated frame encoded on the last 4 bytes (uint32). 549 550 It is encoded on the first 8 bytes like this: 551 552 header := [8]byte{STREAM_TYPE, 0, 0, 0, SIZE1, SIZE2, SIZE3, SIZE4} 553 554 `STREAM_TYPE` can be: 555 556 - 0: stdin (will be written on stdout) 557 - 1: stdout 558 - 2: stderr 559 560 `SIZE1, SIZE2, SIZE3, SIZE4` are the 4 bytes of 561 the uint32 size encoded as big endian. 562 563 **PAYLOAD** 564 565 The payload is the raw stream. 566 567 **IMPLEMENTATION** 568 569 The simplest way to implement the Attach protocol is the following: 570 571 1. Read 8 bytes 572 2. chose stdout or stderr depending on the first byte 573 3. Extract the frame size from the last 4 byets 574 4. Read the extracted size and output it on the correct output 575 5.

the file format version 1332 2. `json`: detailed layer information, similar to `docker inspect layer_id` 1333 3. `layer.tar`: A tarfile containing the filesystem changes in this layer 1334 1335 The `layer.tar` file will contain `aufs` style `.wh..wh.aufs` files and directories 1336 for storing attribute changes and deletions. 1337 1338 If the tarball defines a repository, there will also be a `repositories` file at 1339 the root that contains a list of repository and tag names mapped to layer IDs. 1340 1341 ``` 1342 {"hello-world": 1343 {"latest": "565a9d68a73f6706862bfe8409a7f659776d4d60a8d096eb4a3cbce6999cc2a1"} 1344 } 1345 ``` 1346 1347 # 3. Going further 1348 1349 ## 3.1 Inside `docker run` 1350 1351 As an example, the `docker run` command line makes the following API calls: 1352 1353 - Create the container 1354 1355 - If the status code is 404, it means the image doesn't exist: 1356 - Try to pull it 1357 - Then retry to create the container 1358 1359 - Start the container 1360 1361 - If you are not in detached mode: 1362 - Attach to the container, using logs=1 (to have stdout and 1363 stderr from the container's start) and stream=1 1364 1365 - If in detached mode or only stdin is attached: 1366 - Display the container's id 1367 1368 ## 3.2 Hijacking 1369 1370 In this version of the API, /attach, uses hijacking to transport stdin, 1371 stdout and stderr on the same socket. This might change in the future. 1372 1373 ## 3.3 CORS Requests 1374 1375 To enable cross origin requests to the remote api add the flag 1376 "--api-enable-cors" when running docker in daemon mode. 1377 1378 $ docker -d -H="192.168.1.9:2375" --api-enable-cors
