Official Docker support for iipsrv 1.1

[manoaman]

Hi @ruven

Is there an official release of iipsrv 1.1 in Docker? And I'm also interested to know if Ubuntu 20.04 LTS comes with the latest 1.1.

Thank you, manoaman

No, there's no official one. It would be a good idea to have one - I'll look into it.

And I'm also interested to know if Ubuntu 20.04 LTS comes with the latest 1.1.

Yes indeed it does: https://packages.ubuntu.com/focal/iipimage-server

Thanks @ruven . That would be great to have. Looking forward to the official release! Tried on my machine and seemed to worked. Attaching sample Dockerfile and entrypoint script.

% docker build -t iipimagesrv1.1 .
% docker run -dit --name iipimage  -p 9000:9000 -v ./images:/mnt/images -v ./config/:/etc/apache2/mods-enabled/ -v ./log/:/tmp/
 iipimagesrv1.1

Can't seem to figure out using custom iipsrv.conf with Docker. Logging seems to go /tmp/iipsrv.log and MEMCACHED_SERVERS don't seem to reflect the change. I'm only seeing localhost used.

@ruven has there been a change to configuring MEMCACHED_SERVERS with iipsrv1.1 ? And should iipsrv.fcgi run with root user?

# Create a directory for the iipsrv binary
ScriptAlias /fcgi-bin/ "/usr/lib/iipimage-server/"

# Set the options on that directory
<Directory "/fcgi-bin/">
   AllowOverride None
   Options None
   <IfModule mod_version.c>
     <IfVersion < 2.4>
       Order allow,deny
       Allow from all
     </IfVersion>
     <IfVersion >= 2.4>
       Require all granted
     </IfVersion>
   </IfModule>

   # Set the module handler
   AddHandler fcgid-script .fcgi
</Directory>

# Set our environment variables for the IIP server
FcgidInitialEnv VERBOSITY "6"
FcgidInitialEnv LOGFILE "/var/log/iipsrv.log"
FcgidInitialEnv MAX_IMAGE_CACHE_SIZE "128"
FcgidInitialEnv JPEG_QUALITY "90"
FcgidInitialEnv MAX_CVT "5000"
FcgidInitialEnv MEMCACHED_SERVERS "localhost,test2.com:11211,test3.com:11211,test3.com:11211"
FcgidInitialEnv MEMCACHED_TIMEOUT "86400"

# Define the idle timeout as unlimited and the number of
# processes we want
FcgidIdleTimeout 0
FcgidMaxProcessesPerClass 50

Hello,

for information, I made one some years ago (we use iipsrv (from the source) with an nginx in front (a specific version)). https://github.com/cytomine/Dockerfiles/blob/master/iipbase/Dockerfile https://github.com/cytomine/Dockerfiles/blob/master/iipOfficial/Dockerfile

I think the best way is to start from an official ubuntu image and install form package.

Have a nice day ! :-)

@geektortoise thank you! it is a good example for me to look into.

@ruven I'm a bet confused with the latest iipsrv1.1 on Ubutu20.04 running with Apache. And I was wondering if you don't mind answering to questions.

Do I need to install prerequisite libraries, Apache2, and explicitly load a2enmod on either iipsrv or fcgid to use mod_fastcgi or mod_fcgid? And use systemd to auto start iipsrv?

https://iipimage.sourceforge.io/2012/05/new-debian-and-ubuntu-packages-released/

Second question. If I start iipsrv from a command line, can I pass along iipsrv.conf or fcgid.conf to overwrite config values? Is there a way to know where iipsrv is getting the config values from?

Thanks for your help.

i'm using this docker compose https://github.com/medialibraryonline/iipsrv-docker two containers: one running iipsrv with spawn-fcgi, the other running nginx.

I've made an official docker image for the 1.2 release (based on Alpine Linux). It uses the Alpine iipsrv package with Lighttpd as a web front-end to provide a fully functional environment for IIPImage:

https://hub.docker.com/r/iipsrv/iipsrv

Let me know if you have any comments or suggestions for improving the Docker image.

[atomotic]

great, thanks! Is the build automated and could be made for aarch64 too? I was using lately this https://github.com/atomotic/iipsrv.docker (not very optimized, the image is quite big), will switch to your official image.

[ruven]

Yes, this image is nice and small - only about 12MB!

I've looked into making multi-arch builds and it's not too difficult. I've updated the images to include all the architectures available with Alpine linux: https://hub.docker.com/r/iipsrv/iipsrv
