Yesterday I was checking deployd and wanted to try it out. Doing as the docs said, when I to started deployd It stuck on
starting deployd v0.6.10...
After going through the issues on github i finally found this old-ish similar issue which was still unresolved. To solve it start
monogd as a seperate process and run deployd as
dpd -P 27017 -H localhost -n testing-deployd -d
If you have a fix for the issue, dont feel shy to send a pull request or comment on the thread. Everyone loves contributions :D
