Jenkins Docker image says insufficient memory for JRE to continue, but server should have more than enough?

Docker Hub

So I’m trying to mount a CI with Jenkins on an “old” laptop I had here which has 16GB RAM. I installed Alpine Linux 3.6 on an SSD and installed Docker.

Now I’m trying to run the official Jenkins Docker image with this command:

docker run -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts

but I get this error:

docker run -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts
OpenJDK 64-Bit Server VM warning: INFO: os::commit_memory(0x0000605179000000, 2555904, 1) failed; error='Operation not permitted' (errno=1)
#
# There is insufficient memory for the Java Runtime Environment to continue.
# Native memory allocation (mmap) failed to map 2555904 bytes for committing reserved memory.
# An error report file with more information is saved as:
# /tmp/hs_err_pid7.log

I should have more than enough memory for that? Maybe I installed Alpine Linux in a wrong manner?

Some more info:
