Error when scaling docker containers

  • When running more than instance of jsreport by scaling up the containers, I get the following error.

    2018-09-18T03:21:53.063Z - error: Error when performing remote sync Error: EEXIST: file already exists, open '/app/data/fs.lock'

    What am I missing?

  • You use multiple containers mapped to the same volume where you store jsreport data (templates...) right?

  • That's exactly correct. Whats a proper pattern to deploy when I need to scale?

  • This should work and it looks like our bug at the first glance.
    We take a look and come back to you.

    What jsreport version you have?

  • Do run docker host on windows or linux?

  • pulled the latest from docker hub yesterday.
    Running on centos 7

  • Thank you.
    I fixed the issue in jsreport-fs-store@2.2.0 by increasing timeouts for lock files used to avoid concurrent writes to the file system.

    You need to create your docker images which has npm i jsreport-fs-store@2.2.0 or wait until we release the next jsreport hotfix.
    Not sure when we release it.

  • Thanks for the quick response. I will try building my own image with this change.
