Pmm v3 update not possible

Percona Monitoring and Management (PMM) PMM 3.x
1

Hi,

Unfortunately, I can’t update to PMM v3.1.0 via the UI. When I try, I get the following error:

“Failed to check watchtower host”

Both Docker Compose configurations use the same WATCHTOWER_HTTP_API_TOKEN. The update page also correctly displays information about my PMM instance.

Do you have any idea why this error occurs?

Thanks!

Hey @Marvin_Stelter,
I take it you launched a docker container with watchtower? And you did this inside a dedicated docker network? And both watchtower, and pmm-server containers are in the same network?

Hi, i have same issue

Im having the same issue here, both containers pmm-server and watchtower are in the same network , token and watchtower hostname are correctly set , but the update app wizard still complain about it is unable to check watchtower host.

I made it manually .
Stop and remove ctnr

docker stop pmm-server && docker rm pmm-server

percona/pmm-server:3.2.0

docker run --detach --restart always \
--publish 443:8443 \
--env PMM_WATCHTOWER_HOST=9436f0c11113 \
--env PMM_WATCHTOWER_TOKEN=28955d573bd9f89e267aeb9d0a11111c \
--volume pmm-data:/srv \
--network=pmm-network \
--name pmm-server \
percona/pmm-server:3.2.0

check new version

docker exec -it pmm-server bash -c 'pmm-admin --version'

results

Hi, can you run docker inspect pmm-server and docker inspect watchtower and share output, please? Could you also share how did you setup it?
