Brief introduction 8 9 - The Remote API has replaced `rcli`. 10 - The daemon listens on `unix:///var/run/docker.sock` but you can 11 [Bind Docker to another host/port or a Unix socket]( 12 /articles/basics/#bind-docker-to-another-hostport-or-a-unix-socket). 13 - The API tends to be REST, but for some complex commands, like `attach` 14 or `pull`, the HTTP connection is hijacked to transport `STDOUT`, 15 `STDIN` and `STDERR`. 16 17 # 2.

If `name` is an image ID, similarly only tha 1499 image (and its parents) are returned, but with the exclusion of the 1500 'repositories' file in the tarball, as there were no image names referenced. 1501 1502 See the [image tarball format](#image-tarball-format) for more details. 1503 1504 **Example request** 1505 1506 GET /images/ubuntu/get 1507 1508 **Example response**: 1509 1510 HTTP/1.1 200 OK 1511 Content-Type: application/x-tar 1512 1513 Binary data stream 1514 1515 Status Codes: 1516 1517 - **200** – no error 1518 - **500** – server error 1519 1520 ### Get a tarball containing all images. 1521 1522 `GET /images/get` 1523 1524 Get a tarball containing all images and metadata for one or more repositories. 1525 1526 For each value of the `names` parameter: if it is a specific name and tag (e.g. 1527 ubuntu:latest), then only that image (and its parents) are returned; if it is 1528 an image ID, similarly only that image (and its parents) are returned and there 1529 would be no names referenced in the 'repositories' file for this image ID. 1530 1531 See the [image tarball format](#image-tarball-format) for more details. 1532 1533 **Example request** 1534 1535 GET /images/get?names=myname%2Fmyapp%3Alatest&names=busybox 1536 1537 **Example response**: 1538 1539 HTTP/1.1 200 OK 1540 Content-Type: application/x-tar 1541 1542 Binary data stream 1543 1544 Status Codes: 1545 1546 - **200** – no error 1547 - **500** – server error 1548 1549 ### Load a tarball with a set of images and tags into docker 1550 1551 `POST /images/load` 1552 1553 Load a set of images and tags into the docker repository. 1554 See the [image tarball format](#image-tarball-format) for more details. 1555 1556 **Example request** 1557 1558 POST /images/load 1559 1560 Tarball in body 1561 1562 **Example response**: 1563 1564 HTTP/1.1 200 OK 1565 1566 Status Codes: 1567 1568 - **200** – no error 1569 - **500** – server error 1570 1571 ### Image tarball format 1572 1573 An image tarball contains one directory per image layer (named using its long ID), 1574 each containing three files: 1575 1576 1. `VERSION`: currently `1.0` - the file format version 1577 2. `json`: detailed layer information, similar to `docker inspect layer_id` 1578 3. `layer.tar`: A tarfile containing the filesystem changes in this layer 1579 1580 The `layer.tar` file will contain `aufs` style `.wh..wh.aufs` files and directories 1581 for storing attribute changes and deletions. 1582 1583 If the tarball defines a repository, there will also be a `repositories` file at 1584 the root that contains a list of repository and tag names mapped to layer IDs. 1585 1586 ``` 1587 {"hello-world": 1588 {"latest": "565a9d68a73f6706862bfe8409a7f659776d4d60a8d096eb4a3cbce6999cc2a1"} 1589 } 1590 ``` 1591 1592 ### Exec Create 1593 1594 `POST /containers/(id)/exec` 1595 1596 Sets up an exec instance in a running container `id` 1597 1598 **Example request**: 1599 1600 POST /containers/e90e34656806/exec HTTP/1.1 1601 Content-Type: application/json 1602 1603 { 1604 "AttachStdin": false, 1605 "AttachStdout": true, 1606 "AttachStderr": true, 1607 "Tty": false, 1608 "Cmd": [ 1609 "date" 1610 ], 1611 } 1612 1613 **Example response**: 1614 1615 HTTP/1.1 201 OK 1616 Content-Type: application/json 1617 1618 { 1619 "Id": "f90e34656806" 1620 } 1621 1622 Json Parameters: 1623 1624 - **AttachStdin** - Boolean value, attaches to stdin of the exec command. 1625 - **AttachStdout** - Boolean value, attaches to stdout of the exec command. 1626 - **AttachStderr** - Boolean value, attaches to stderr of the exec command. 1627 - **Tty** - Boolean value to allocate a pseudo-TTY 1628 - **Cmd** - Command to run specified as a string or an array of strings. 1629 1630 1631 Status Codes: 1632 1633 - **201** – no error 1634 - **404** – no such container 1635 1636 ### Exec Start 1637 1638 `POST /exec/(id)/start` 1639 1640 Starts a previously set up exec instance `id`. If `detach` is true, this API 1641 returns after starting the `exec` command. Otherwise, this API sets up an 1642 interactive session with the `exec` command. 1643 1644 **Example request**: 1645 1646 POST /exec/e90e34656806/start HTTP/1.1 1647 Content-Type: application/json 1648 1649 { 1650 "Detach": false, 1651 "Tty": false, 1652 } 1653 1654 **Example response**: 1655 1656 HTTP/1.1 201 OK 1657 Content-Type: application/json 1658 1659 {{ STREAM }} 1660 1661 Json Parameters: 1662 1663 - **Detach** - Detach from the exec command 1664 - **Tty** - Boolean value to allocate a pseudo-TTY 1665 1666 Status Codes: 1667 1668 - **201** – no error 1669 - **404** – no such exec instance 1670 1671 **Stream details**: 1672 Similar to the stream behavior of `POST /container/(id)/attach` API 1673 1674 ### Exec Resize 1675 1676 `POST /exec/(id)/resize` 1677 1678 Resizes the tty session used by the exec command `id`. 1679 This API is valid only if `tty` was specified as part of creating and starting the exec command. 1680 1681 **Example request**: 1682 1683 POST /exec/e90e34656806/resize HTTP/1.1 1684 Content-Type: plain/text 1685 1686 **Example response**: 1687 1688 HTTP/1.1 201 OK 1689 Content-Type: plain/text 1690 1691 Query Parameters: 1692 1693 - **h** – height of tty session 1694 - **w** – width 1695 1696 Status Codes: 1697 1698 - **201** – no error 1699 - **404** – no such exec instance 1700 1701 # 3. Going further 1702 1703 ## 3.1 Inside `docker run` 1704 1705 As an example, the `docker run` command line makes the following API calls: 1706 1707 - Create the container 1708 1709 - If the status code is 404, it means the image doesn't exist: 1710 - Try to pull it 1711 - Then retry to create the container 1712 1713 - Start the container 1714 1715 - If you are not in detached mode: 1716 - Attach to the container, using logs=1 (to have stdout and 1717 stderr from the container's start) and stream=1 1718 1719 - If in detached mode or only stdin is attached: 1720 - Display the container's id 1721 1722 ## 3.2 Hijacking 1723 1724 In this version of the API, /attach, uses hijacking to transport stdin, 1725 stdout and stderr on the same socket. This might change in the future. 1726 1727 ## 3.3 CORS Requests 1728 1729 To enable cross origin requests to the remote api add the flag 1730 "--api-enable-cors" when running docker in daemon mode. 1731 1732 $ docker -d -H="192.168.1.9:2375" --api-enable-cors
