ImageMagick Static Binaries for AWS Lambda

imagemagick.bash

#!/usr/bin/env bash

# Must be run on an Amazon Linux AMI that matches AWS Lambda's runtime which can be found at:
# https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html
#
# As of May 21, 2019, this is:
# Amazon Linux AMI 2018.03.0 (ami-0756fbca465a59a30)
#
# You need to prepend PATH with the folder containing these binaries in your Lambda function 
# to ensure these newer binaries are used.
#
# In a NodeJS runtime, you would add something like the following to the top of
# your Lambda function file:
# process.env['PATH'] = process.env['LAMBDA_TASK_ROOT'] + '/imagemagick/bin:' + process.env['PATH']
#
# This works with both ImageMagick v6.x and v7.x
# version=6.9.10-23
version=7.0.8-45

sudo yum -y install libpng-devel libjpeg-devel libtiff-devel gcc
curl -O https://imagemagick.org/download/ImageMagick-$version.tar.gz 
tar zxvf ImageMagick-$version.tar.gz
cd ImageMagick-$version 
./configure --prefix=/var/task/imagemagick --enable-shared=no --enable-static=yes
make
sudo make install
tar zcvf ~/imagemagick.tgz /var/task/imagemagick/

This thread has been super helpful - in that I now finally have a working version of IM with PDF support running on Lambda / Node v10.x
However it's also left me some questions :
@ronaksavla - did AWS say why they removed the convert modules? And do we mean the modules like /usr/lib64/ImageMagick-6.7.8/modules-Q16/coders/pdf.la ?
What caught me out during this journey is that Lambda/Node8.10 actually has ImageMagick 6.7.8.9-15.21.amzn1 RPM already installed. (I'm not sure if this was a recent change?) But convert & identify etc work natively out of the box, however it doesn't include PDF support. @bensie - with your script above, I'm pretty sure that won't give you extras such as PDF support, and will rely on the libs / modules included in the Lambda AMI for Node8.10. In which case - why not just use the ImageMagick 6.7.8.9 already in Lambda/Node8.10 ?
@chaddjohnson - thanks for the detailed tips on GS / PDF / gslib config. I found when using Lambda Node10.x I then also had to copy across many of the missing libs & config xmls like delegate.xml. Did you do this also? Or is this using Node8.10 and using the preinstalled IM libs?

@danhouldsworth Glad that was helpful. I am still running this stuff on 8.10 — haven’t tried it in 10.x and don’t plan to for a while. I’m using preinstalled stuff except for the convert binary I compiled and the gs bin I added.

@chaddjohnson Thank you for sharing!
@danhouldsworth I had the copy the libraries over as well.
@jp928 I had to do the same thing, copy all the files in the tmp directory and chmod them in code. Then set PATH. Im not sure what everyone else is doing.

For the missing libraries I had to run the command "ldd" on the binaries to see what libraries were missing. EX:
ldd convert

@adnascent the ldd convert command ended up missing some libraries for me, such as libxml2.so.2 which is not listed as a shared lib for either convert or gs. Were you also checking shared libs for any other library?

I've been trying to get this working over the past couple of weeks on node 10 (also tried downgrading to node 8 and got the same errors as @ronaksavla). I'm considering switching gears and trying this with Lambda Layers. Has anyone tried with Layers before?

I've had success using layers like this on node10.x - https://github.com/serverlesspub/imagemagick-aws-lambda-2 - it worked out of the box, and then with some custom modifications. Going to approach ghostscript the same way.

Updated instructions for nodejs10.x runtime

I was able to get this working. This should also work for nodejs12.x.

ImageMagick

Before proceeding, set up a Lambda Execution Environment. See https://docs.aws.amazon.com/lambda/latest/dg/current-supported-versions.html. The AMI amzn2-ami-hvm-2.0.20190313-x86_64-gp2 was used for this compilation.

1. On the server, download the latest version of ImageMagick 6 or 7 from https://imagemagick.org/download/.
2. Extract the source.
3. Install dependencies: sudo yum install libpng-devel libjpeg-devel libtiff-devel gcc ImageMagick-devel xz-devel.x86_64 fontconfig-devel.x86_64 libxml2-devel.x86_64 libtool-ltdl-devel lcms2-devel.
4. Run ./configure --prefix=/var/task/imagemagick --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared=no --enable-static=yes --with-modules --with-perl=no --with-x=no --with-gslib=no --with-lcms --without-rsvg --with-xml --without-dps --disable-hdri --with-quantum-depth=8 --disable-openmp in the source directory.
   1. Note the intentional use of --with-gslib=no. This forces use of the gs binary rather than the system library. See this discussion for details.
5. Run make in the source directory.
6. Run sudo make install in the source directory.
7. Copy only the needed built files from the /var/task/imagemagick/bin directory into a local clone of your repository.
   1. If building ImageMagick 7, symlinks are present in the bin directory, so be sure to preserve symlinks using zip --symlinks or tar zcf.
8. Copy libbz2.so.1, libexpat.so.1, libfontconfig.so.1, libfreetype.so.6, libgs.so.9, libjbig.so.2.0, libjpeg.so.62, liblcms2.so.2, liblzma.so.5, libpng15.so.15, libtiff.so.5, and libxml2.so.2 to lib/ in your repository from the server in /usr/lib64/. Be sure to copy the files that these symlink to, not the symlinks.

Then in the Lambda function, above the handler definition, include the following:

process.env['PATH'] = `${process.env['LAMBDA_TASK_ROOT']}/bin:${process.env['PATH']}`;
process.env['MAGICK_CONFIGURE_PATH'] = `${process.env['LAMBDA_TASK_ROOT']}/etc/ImageMagick`;

I also copied /etc/ImageMagick from the ami instance into my repository and am setting MAGICK_CONFIGURE_PATH -- I don't know if this is necessary:

process.env['MAGICK_CONFIGURE_PATH'] = `${process.env['LAMBDA_TASK_ROOT']}/etc/ImageMagick`;

Ghostscript (for PDF support)

1. Download the latest version of Ghostscript for Linux x86 (64 bit) from https://www.ghostscript.com/download/gsdnld.html.
2. Copy the gs-*-linux-x86_64 executable to bin/gs in your repository.
3. Ensure the bin/gs binary is executable via chmod +x bin/gs.
4. Copy libgs.so.9 to lib/ from the server in /usr/lib64/. Be sure to copy the file that this symlinks to, not the symlink.

@chaddjohnson can you please write command for step 7 and 8 I am very new to linux , it will help , I am just stuck in this,
also there is no libexpat library in usr/lib64

@singhadarsh93 Should be something like this:

7. Run approximately these commands:

   On the server:

   cd /var/task/imagemagick
   tar zcf bin.tar.gz bin/convert bin/composite bin/identify
   

   On your computer (replace xxx.xxx.xxx.xxx with the server IP):

   ssh -i key.pem [email protected] 'cat /var/task/imagemagick/bin.tar.gz' > bin.tar.gz
   tar zxf bin.tar.gz
   

   Then there should be a bin directory on your local machine with the binaries.

8. Run approximately these commands:

   On the server:

   mkdir /home/ec2-user/lib
   cd /usr/lib64
   cp -L libbz2.so.1 libexpat.so.1 libfontconfig.so.1 libfreetype.so.6 libgs.so.9 libjbig.so.2.0 libjpeg.so.62 liblcms2.so.2 liblzma.so.5 libpng15.so.15 libtiff.so.5 and libxml2.so.2 /home/ec2-user/lib/
   cd /home/ec2-user
   tar zcf lib.tar.gz lib/
   

   On your computer:

   ssh -i key.pem [email protected] 'cat lib.tar.gz' > lib.tar.gz
   tar zxf lib.tar.gz
   

   Then there should be a lib directory on your local machine with the .so files.

Not sure why libexpat isn't present. Maybe try yum install expat-devel. If that doesn't work, try searching via yum search expat, and install the expat devel 64-bit package.

   var IM_PATH = process.env['LAMBDA_TASK_ROOT'] + "/imagemagick/bin/";
   process.env['LD_LIBRARY_PATH'] = '/var/task/imagemagick/lib/';
   process.env['PATH'] = process.env['PATH'] + ':' + IM_PATH;
   var gm = require('gm').subClass({
     imageMagick: true,
    appPath: '/var/task/imagemagick/bin/',
  });

remember to put the imagemagick floder in the root folder

I tried this after installing imagemagick in AWS lambda, but it automatically appends the path with "identify". And I dont know, where is that written.

could you share the final stack of files?

Instructions for Python 3.8

My use-case was to convert pages in a PDF to PNG via wand. I followed the instructions provided by @chaddjohnson at https://gist.github.com/bensie/56f51bc33d4a55e2fc9a#gistcomment-3133859 but was getting errors when using wand. Following are the instructions on how I was able to resolve those by doing some slight adjustments:

1. Start an EC2 instance and SSH into it. I used the AMI amzn2-ami-hvm-2.0.20210126.0-x86_64-gp2.
2. Download ImageMagick 6.9.11.

   wget https://download.imagemagick.org/ImageMagick/download/ImageMagick-6.9.11-60.tar.gz

3. Extract the folder.

   tar zxvf ImageMagick-6.9.11-60.tar.gz

4. cd into the extracted folder.

   cd ImageMagick-6.9.11-60

5. Edit the policy.xml file to allow PDF to PNG conversion.

   nano config/policy.xml

   I copy-pasted the following content but you can modify it as needed.

   <?xml version="1.0" encoding="UTF-8"?>
   <!DOCTYPE policymap [
   <!ELEMENT policymap (policy)+>
   <!ELEMENT policy (#PCDATA)>
   <!ATTLIST policy domain (delegate|coder|filter|path|resource) #IMPLIED>
   <!ATTLIST policy name CDATA #IMPLIED>
   <!ATTLIST policy rights CDATA #IMPLIED>
   <!ATTLIST policy pattern CDATA #IMPLIED>
   <!ATTLIST policy value CDATA #IMPLIED>
   ]>
   <!--
     Configure ImageMagick policies.
   
     Domains include system, delegate, coder, filter, path, or resource.
   
     Rights include none, read, write, and execute.  Use | to combine them,
     for example: "read | write" to permit read from, or write to, a path.
   
     Use a glob expression as a pattern.
   
     Suppose we do not want users to process MPEG video images:
   
       <policy domain="delegate" rights="none" pattern="mpeg:decode" />
   
     Here we do not want users reading images from HTTP:
   
       <policy domain="coder" rights="none" pattern="HTTP" />
   
     Lets prevent users from executing any image filters:
   
       <policy domain="filter" rights="none" pattern="*" />
   
     The /repository file system is restricted to read only.  We use a glob
     expression to match all paths that start with /repository:
     
       <policy domain="path" rights="read" pattern="/repository/*" />
   
     Let's prevent possible exploits by removing the right to use indirect reads.
   
       <policy domain="path" rights="none" pattern="@*" />
   
     Any large image is cached to disk rather than memory:
   
       <policy domain="resource" name="area" value="1GB"/>
   
     Define arguments for the memory, map, area, width, height, and disk resources
     with SI prefixes (.e.g 100MB).  In addition, resource policies are maximums
     for each instance of ImageMagick (e.g. policy memory limit 1GB, -limit 2GB
     exceeds policy maximum so memory limit is 1GB).
   -->
   <policymap>
     <!-- <policy domain="resource" name="temporary-path" value="/tmp"/> -->
     <policy domain="resource" name="memory" value="256MiB"/>
     <policy domain="resource" name="map" value="512MiB"/>
     <policy domain="resource" name="width" value="16KP"/>
     <policy domain="resource" name="height" value="16KP"/>

     <!-- in order to avoid to get image with password text -->
     <policy domain="path" rights="none" pattern="@*"/>
     <policy domain="cache" name="shared-secret" value="passphrase" stealth="true"/>
     <!-- disable ghostscript format types -->
     <policy domain="coder" rights="none" pattern="PS" />
     <policy domain="coder" rights="none" pattern="EPI" />
     <policy domain="coder" rights="read|write" pattern="PDF" />
     <policy domain="coder" rights="none" pattern="XPS" />
     <policy domain="coder" rights="read|write" pattern="LABEL" />
   </policymap>

6. Configure and install ImageMagick.

   ./configure --prefix=/var/task/imagemagick --sysconfdir=/etc --datadir=/usr/share --includedir=/usr/include --libdir=/usr/lib64 --libexecdir=/usr/libexec --localstatedir=/var --sharedstatedir=/var/lib --mandir=/usr/share/man --infodir=/usr/share/info --enable-shared=no --enable-static=yes --with-modules --with-perl=no --with-x=no --with-gslib=no --with-lcms --without-rsvg --with-xml --without-dps --disable-hdri --with-quantum-depth=8 --disable-openmp
   make
   sudo make install

7. Copy the required .so files.

   mkdir lib
   cd /usr/lib64/
   cp -L libbz2.so.1 libexpat.so.1 libfontconfig.so.1 libfreetype.so.6 libgs.so.9 libjbig.so.2.0 libjpeg.so.62 liblcms2.so.2 liblzma.so.5 libpng15.so.15 libtiff.so.5 libxml2.so.2 libMagickCore-6.Q16.so.6 libMagickWand-6.Q16.so.6 libXext.so.6 libXt.so.6 libltdl.so.7 libSM.so.6 libICE.so.6 libX11.so.6 libgomp.so.1 libuuid.so.1 libxcb.so.1 libXau.so.6 libMagickCore-6.Q8.so.6 libMagickWand-6.Q8.so.6 libm.so.6 libz.so.1 libjasper.so.1 /home/ec2-user/lib/
   cp -r ImageMagick-6.9.10/ ImageMagick-6.9.11/ /home/ec2-user/lib/
   cd /home/ec2-user
   tar zcf lib.tar.gz lib/

   Copy the lib.tar.gz file from the server to your local machine.
8. Copy the required binary files.

   cd /var/task/imagemagick
   sudo tar zcf bin.tar.gz bin/
   cp bin.tar.gz /home/ec2-user/bin.tar.gz 

   Copy the bin.tar.gz file from the server to your local machine.
9. Copy the XML files required by ImageMagick.

   cd /etc/
   sudo tar zcf etc.tar.gz ImageMagick-6/
   cp etc.tar.gz /home/ec2-user/etc.tar.gz

   Copy the etc.tar.gz file from the server to your local machine.
10. Close the SSH session.
11. On your local machine, extract the contents of the 3 *.tar.gz files.
12. Download ghostscript from https://github.com/ArtifexSoftware/ghostpdl-downloads/releases/download/gs9533/ghostscript-9.53.3-linux-x86_64.tgz and extract the ghostscript binary into the bin/ folder and rename it to gs. Run chmod +x bin/gs to make it executable.
13. Compress the 3 - lib, bin and etc - folders into a ZIP file. The tree structure of the ZIP file would look like

    file.zip/
    |-- bin
    |   |-- convert
    |   |-- ...
    |   `-- gs
    |-- etc
    |   `-- ImageMagick-6
    |       |-- coder.xml
    |       |-- ...
    |       `-- type.xml
    `-- lib
        |-- ImageMagick-6.9.10
        |   |-- config-Q16
        |   |   `-- configure.xml
        |   `-- modules-Q16
        |       |-- coders
        |       |   |-- aai.la
        |       |   |-- ...
        |       |   `-- yuv.so
        |       `-- filters
        |           |-- analyze.la
        |           `-- analyze.so
        |-- ImageMagick-6.9.11
        |   |-- config-Q8
        |   |   `-- configure.xml
        |   `-- modules-Q8
        |       |-- coders
        |       |   |-- aai.la
        |       |   |-- ...
        |       |   `-- yuv.so
        |       `-- filters
        |           |-- analyze.la
        |           `-- analyze.so
        |-- libICE.so.6
        |-- ...
        `-- libz.so.1
    

    I have used ... wherever the folder contained more than 2 files to denote that there are more files present.
14. Create a Python 3.8 runtime compatible layer on AWS Lambda and use the ZIP created in step 13.
15. Add the layer to your AWS Lambda function code.
16. Update environment variables in your lambda function.

    import os
    os.environ["PATH"] = f"/opt/bin:{os.environ['PATH']}"
    os.environ["LD_LIBRARY_PATH"] = f"/opt/lib:{os.environ['LD_LIBRARY_PATH']}"
    os.environ["MAGICK_HOME"] = "/opt/"
    os.environ["WAND_MAGICK_LIBRARY_SUFFIX"] = "-6.Q8"
    os.environ["MAGICK_CONFIGURE_PATH"] = "/opt/etc/ImageMagick-6/"
    os.environ["MAGICK_CODER_MODULE_PATH"] = "/opt/lib/ImageMagick-6.9.11/modules-Q8/coders/"

Note: If the size of the uncompressed ZIP file is too large and you reach AWS Lambda size limits, remove the binaries that you don't need from the bin/ folder. In my case, I only kept Magick-config, MagickCore-config, MagickWand-config, Wand-config, convert and gs and removed others.

NOTE: I also have a ready-to-use ZIP file uploaded at https://github.com/samkit-jain/aws-lambda-imagemagick-ghostscript

Where to Place this Code ?

16. Update environment variables in your lambda function.

import os
os.environ["PATH"] = f"/opt/bin:{os.environ['PATH']}"
os.environ["LD_LIBRARY_PATH"] = f"/opt/lib:{os.environ['LD_LIBRARY_PATH']}"
os.environ["MAGICK_HOME"] = "/opt/"
os.environ["WAND_MAGICK_LIBRARY_SUFFIX"] = "-6.Q8"
os.environ["MAGICK_CONFIGURE_PATH"] = "/opt/etc/ImageMagick-6/"
os.environ["MAGICK_CODER_MODULE_PATH"] = "/opt/lib/ImageMagick-6.9.11/modules-Q8/coders/"

@R-Harishkumar You may place the code at the top of the Python file.

@samkit-jain

I created the layer with your ZIP file and added it to my lambda, along with the code from step 16,
but when I try to do: from wand.image import Image
I get this error: Unable to import module 'lambda_function': No module named 'wand'

And if I try to package wand myself and add it then I get the error where wand doesn't find the shared library for ImageMagick.

Is there any other step you took to get Wand working in AWS Lambda?

Hi @ClickheadZ Adding the ZIP file as a layer would give you the required libraries that you want at the OS level to communicate with imagemagick, gs, ... You still need the pip package files in your lambda archive. Did you add Wand as a dependency in your lambda function archive? Example here.

@samkit-jain Thanks for the response! I had not added it properly, I repackaged and deployed a zip now and I'm getting a different error, not sure what I did wrong.

Here are the steps I took to package Wand:

• Connect to an EC2 instance
• pip install --target=package wand, pip install --target=package magickwand
• scp the package to my computer, and zip the package along with my lambda function as per AWS zip deployment instructions

In lambda console, my lambda structure now looks like this:

myLambdaFunction
      - magickwand
      - magickwand-0.2.dist-info
      - wand
      - Wand-0.6.7.dist-info
      lambda_function.py

And when i try from wand.image import Image I now get the error message : Unable to import module 'lambda_function': MagickWand shared library not found.\nYou probably had not installed ImageMagick library despite the fact that I have deployed the imagemagick/ghostscript zip as a layer for this lambda and added it. Did I do something wrong in the Wand packaging or is the problem my lambda layer?

@ClickheadZ Facing same issue, were you able to find a fix?

Thanks~ It's work for me !!! But I found a small problem while using it：
curl download url: curl -O https://imagemagick.org/download/ImageMagick-$version.tar.gz , it will return 404 http status...
the ture url is: https://download.imagemagick.org/archive/ImageMagick-$version.tar.xz
