Have you ever thought about running your own DX cluster node? I must admit for a long time I didn't use to think I needed it until recently when, in order to speed up NKCCluster development, it became apparent to me that a DX cluster node I could easily deploy in a CI environment would considerably speed up my development process.
Although DX Spider Installation is well documented, I wanted something that I could "fire & forget" and spin up a running DX cluster node in seconds. It seemed to me that a Docker image would be a very convenient way to achieve this. After some googling, I couldn't find anything on the Internet, although on GitHub there exist several repositories whose contents suggest others had similar idea (unfortunately, with no tangible results).
I thus decided to develop the DX Spider Docker image myself. Although it is still in its early stage, it is already functional enough to bring up a working DX Spider node in seconds. Its source code is in GitHub repository kconkas/dxspider-deployment and the image itself is available in identically named DockerHub repository.
Give it a try and see if you like it. GitHub pull requests and bug reports are very welcome.
Note: this image will only get you a running DX Spider node, but will not link it with any other nodes. If you'd like to link it with another node, you will need to agree this with an owner of another active node and configure your connect file for it. You can find more details about it on the DX Spider Wiki.
Huge thanks to Dirk Koopman (G1TLH), the author of DX Spider, for this invaluable piece of software.
