[yosheng]

I run docker image on my Synology. Using normal setting is fine. But when I try to use FTB and run BlastOff modpack. The server always shwo those messages.

I have been add those setting 「Type = FTB 、 VERSION = 1.7.10、FTB_SERVER_MOD = BlastOffServer.zip、EULA = TRUE」

The modpack have been put on /data. Please help solve the problem..

@RisenZhang I discovered this particular modpack expected the server to be started in the FTB sub-directory. Please give the latest build a try and see if that also fixes the issue for you.

Problem Fix !! I appreciate your help. 👍
Could you tell me what different about debian-latest and latest ?
At first I downloaded debian-latest image to build server. Now I use latest one. It seem like the same, only the size is different?

@RisenZhang , awesome.

Yes, the size difference actually was the ultimate goal of the two image choices, but the reason the latest one is smaller is because it is based on Alpine linux. Alpine turns out to be a good base image since it's lack of bells and whistles and lack of extensive package support is not a big deal for creating small, single-purpose Docker images.
