I am trying to run Docker but I need more memory on my Ubuntu 16.04
free -m
total used free shared buff/cache available
Mem: 7914 4024 3072 83 817 3448
Swap: 8127 14 8113
When I run docker
Setting advertised host to 127.0.0.1.
Operating system RAM available is 3344 MiB, which is less than the lowest
recommended of 5120 MiB. Your system performance may be seriously impacted.
What should I do to get more RAM?Is this possible?

You will need to identify those process using the most memory and decide whether they can be stopped to retrieve memory or not. The top command will help you in this instance. Alternatively, you can vertically scale your system and add more memory to the system.

Use the below command to identify top 10 Memory consuming resources. so that you can trouble accordingly
ps axo %mem,command,pid| sort -nr | head
To drop cache use below command
sync;echo 1 > /proc/sys/vm/drop_caches
