Convert image from docker to singularity

Question

I converted grafana docker image to singularity

sudo singularity build grafana.simg docker://grafana/grafana

But when I try to run it

sudo singularity run grafana.simg 

I get

EROR[12-02|08:38:53] Server shutdown
logger=server reason="Service init failed: failed to connect to database: failed to create SQLite database file "/var/lib/grafana/grafana.db": open /var/lib/grafana/grafana.db: read-only file system" Service init failed: failed to connect to database: failed to create SQLite database file "/var/lib/grafana/grafana.db": open /var/lib/grafana/grafana.db: read-only file system

How can i solve that?

Answer 1

Since Singularity images are read-only by default you need to specify a Bind Path .

Try creating a folder on your host for storing Grafana's data.

mkdir -p grafana/data

After this you should be able to start the container.

singularity run --bind grafana/data:/var/lib/grafana grafana.simg
