Docker image for Swift all-in-one demo deployment

This is an attempt to dockerize the instructions for a Swift All-in-one deployment.

Swift requires xattr to be enabled. With the overlay2 storage driver, Docker
supports extended attributes. However, if you're using the older AUFS storage
driver, it isn't possible for Swift to use storage within the Docker image.
The workaround for this is to mount a volume from a filesystem where xattr is
enabled (e.g. ext4 or xfs).

If you'd like the data to be persistent, you should also store it in an external

##This works:

This uses Docker's storage:

docker build -t bouncestorage/swift-aio .
docker run -P -t bouncestorage/swift-aio
curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing'<port>/auth/v1.0
curl -v -H 'X-Auth-Token: <token-from-x-auth-token-above>' <url-from-x-storage-url-above>
swift -A<port>/auth/v1.0 -U test:tester -K testing stat

To persist data, you can replace the docker run command with the following:

docker run -P -v /path/to/data:/swift/nodes -t bouncestorage/swift-aio

Discover the port by running docker ps, which will give output like this:

ID                  IMAGE                          COMMAND               CREATED             STATUS              PORTS
159caa6f384b        bouncestorage/swift-aio:latest /bin/bash /swift/bin   9 minutes ago       Up 9 minutes        49175->22, 49176->8080

You want the port that is mapped to port 8080 within the Docker image, in this case 49176.

Get an authorization token like this:

curl -v -H 'X-Storage-User: test:tester' -H 'X-Storage-Pass: testing'<port>/auth/v1.0


* About to connect() to port 8080 (#0)
*   Trying connected
> GET /auth/v1.0 HTTP/1.1
> User-Agent: curl/7.22.0 (x86_64-pc-linux-gnu) libcurl/7.22.0 OpenSSL/1.0.1 zlib/ libidn/1.23 librtmp/2.3

* Connection #0 to host left intact

To run the script, store the X-Storage-Url and X-Auth-Token values in environment variables:

export URL=
export TOKEN=AUTH_tk246b80e9b72a42e68a76e0ff2aaaf051

You can then run, which will execute a series of curl commands to create
a container, list various information, put itself into Swift as object
"testcontainer/testobject", and retrieve itself again as "".


Uses supervisord to keep the image running. To get a shell on the container, you can use:

docker exec -it <container name> /bin/bash

Tail /var/log/syslog to see what it's doing.

##Notes on changes from Swift-AIO instructions

  • user and group ids are swift:swift
  • the instructions provide for using a separate partition or a loopback for
    storage, presumably to allow the storage capacity to be strictly limted.
    Neither of these was easy for a Docker n00b to implement, so I've just used
    /swift, with symbolic links in /srv. The storage can be limited at the OS
    level in the Docker image if it's a concern.
  • the Github sources are cloned to /usr/local/src
