I run OrthancDocker with host’s /etc/orthanc dir mapped to container’s.
I use multiples config files but only orthanc.json is read.
Is OrthancDocker image configured to run in single config file mode ?
Can you update it to use config dir instead ?
Looks like you have an extra "/tmp" argument. This will get bindmounted
as a local anonymous volume and your actual volume specification will
get interpreted as the image specification, hence the error. (Best
guess anyway.)
