Title:
Docker registry doesn't stay up and keeps restarting
Status in linux package in Ubuntu:
Incomplete
Status in linux source package in Eoan:
In Progress
Status in linux source package in Focal:
In Progress
Bug description:
Tested kernels:
Focal 5.4.0-31.35
Eoan 5.3.0-53.47
To reproduce:
1) Spin up a cloud image
2) snap install docker
3) auth_folder=/var/snap/docker/common/auth
4) mkdir -p $auth_folder
5) docker run --entrypoint htpasswd registry:2 -Bbn user passwd >
$auth_folder/htpasswd
6) docker run -d -p 5000:5000 --restart=always --name registry \
-v $auth_folder:/auth \
-e "REGISTRY_AUTH=htpasswd" \
-e "REGISTRY_AUTH_HTPASSWD_REALM=Registry Realm" \
-e REGISTRY_AUTH_HTPASSWD_PATH=/auth/htpasswd \
registry:2
On a good kernel 'docker ps' shows something like:
# docker ps
CONTAINER ID IMAGE COMMAND CREATED
STATUS PORTS NAMES
a346b65b4509 registry:2 "/entrypoint.sh /etc…" 14 seconds
ago Up 12 seconds 0.0.0.0:5000->5000/tcp registry
On a bad kernel:
docker ps
CONTAINER ID IMAGE COMMAND CREATED
STATUS PORTS NAMES
0322374f1b1d registry:2 "/entrypoint.sh /etc…" 5 seconds
ago Restarting (2) 1 second ago registry
Note status 'Restarting' on the bad kernel.
This seems to be introduce by any of the following commits:
b3bdda24f1bc UBUNTU: SAUCE: overlayfs: fix shitfs special-casing
6f18a8434050 UBUNTU: SAUCE: overlayfs: use shiftfs hacks only with shiftfs as
underlay
629edd70891c UBUNTU: SAUCE: shiftfs: record correct creator credentials

Kernels that don't have these commits seem fine.
