yum wkhtmltopdf causes deployment error.

[porteaux]

first thanks for sharing this useful document to the global comunity. I have already installed git, gnuplot, and gsl packages. this is what my current config.ruby looks like:

---

These are things that make sense for any Ruby application

Install git in order to be able to bundle gems from git

packages

yum:
git: []
gnuplot: []
gsl: []

wkhtmltopdf: []

commands:

Run rake with bundle exec to be sure you get the right version

add_bundle_exec:
test: test ! -f /opt/elasticbeanstalk/support/.post-provisioning-complete
cwd: /opt/elasticbeanstalk/hooks/appdeploy/pre
command: perl -pi -e 's/(rake)/bundle exec $1/' 11_asset_compilation.sh

Bundle with --deployment as recommended by bundler docs

cf. http://gembundler.com/v1.2/rationale.html under Deploying Your Application

add_deployment_flag:
test: test ! -f /opt/elasticbeanstalk/support/.post-provisioning-complete
cwd: /opt/elasticbeanstalk/hooks/appdeploy/pre
command: perl -pi -e 's/(bundle install)/$1 --deployment/' 10_bundle_install.sh

Vendor gems to a persistent directory for speedy subsequent bundling

make_vendor_bundle_dir:
test: test ! -f /opt/elasticbeanstalk/support/.post-provisioning-complete
command: mkdir /var/app/support/vendor_bundle

Store the location of vendored gems in a handy env var

set_vendor_bundle_var:
test: test ! -f /opt/elasticbeanstalk/support/.post-provisioning-complete
cwd: /opt/elasticbeanstalk/support
command: sed -i '12iexport EB_CONFIG_APP_VENDOR_BUNDLE=$EB_CONFIG_APP_SUPPORT/vendor_bundle' envvars

The --deployment flag tells bundler to install gems to vendor/bundle/, so

symlink that to the persistent directory

symlink_vendor_bundle:
test: test ! -f /opt/elasticbeanstalk/support/.post-provisioning-complete
cwd: /opt/elasticbeanstalk/hooks/appdeploy/pre
command: sed -i '6iln -s $EB_CONFIG_APP_VENDOR_BUNDLE ./vendor/bundle' 10_bundle_install.sh

Don't run the above commands again on this instance

cf. http://stackoverflow.com/a/16846429/283398

z_write_post_provisioning_complete_file:
cwd: /opt/elasticbeanstalk/support
command: touch .post-provisioning-complete

---

when I uncomment:

wkhtmltopdf: []

And then deploy the new version to my eb app.

My eb console for the environment shows:

2013-07-18 09:55:36 UTC-0400 ERROR Failed to deploy application.
2013-07-18 09:55:35 UTC-0400 ERROR Responses from [i-59892133] were received, but the commands failed.
2013-07-18 09:55:22 UTC-0400 INFO Deploying new version to instance(s).

This could fail for any number of reasons. I would investigate by ssh'ing into an instance and running $ yum install wkhtmltopdfto find the error.

Here's another project's config where they have to drop to commands to install certain yum packages: https://github.com/benjamind/delarre.docpad/blob/master/src/documents/posts/deploying-libcouchbase-with-aws-elasticbeanstalk.html.md#using-ebextensions-commands

No success with:

commands:
#install wkhtmltopdf
01-command:
command: yum install xz urw-fonts libXext openssl-devel libXrender
02-command:
command: wget http://code.google.com/p/wkhtmltopdf/downloads/detail?name=wkhtmltopdf-0.10.0_rc1-static-amd64.tar.lzma&can=2&q=
03-command:
command: xz -d wkhtmltopdf-0.10.0_rc1-static-amd64.tar.lzma
04-command:
command: tar -xvf wkhtmltopdf-0.10.0_rc1-static-amd64.tar
05-command:
command: cp wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf

or:

apt:
wkhtmltopdf: []

@porteaux:

wget http://code.google.com/p/wkhtmltopdf/downloads/detail?name=wkhtmltopdf-0.10.0_rc1-static-amd64.tar.lzma&can=2&q=

will not get the tar file, this will do:

wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2

I made that change en when the new commit is deployed the following message is shown:

[Instance: i-aff555d5 Module: AWSEBAutoScalingGroup ConfigSet: null] Failed on instance with return code: 1 Output: ver msg = "%s\n" % self.format(record) File "/usr/lib64/python2.6/logging/init.py", line 654, in format return fmt.format(record) File "/usr/lib64/python2.6/logging/init.py", line 436, in format record.message = record.getMessage() File "/usr/lib64/python2.6/logging/init.py", line 306, in getMessage msg = msg % self.args UnicodeDecodeError: 'ascii' codec can't decode byte 0xe2 in position 366: ordinal not in range(128) Error occurred during build: Command 03-command failed .

This worked:

#install wkhtmltopdf
01-command:
command: yum install xz urw-fonts libXext openssl-devel libXrender
02-command:
command: wget http://wkhtmltopdf.googlecode.com/files/wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2
03-command:
command: tar -xvf wkhtmltopdf-0.11.0_rc1-static-amd64.tar.bz2
04-command:
command: cp wkhtmltopdf-amd64 /usr/bin/wkhtmltopdf

@porteaux thank you very much for sharing your solution! It installed everything correctly, but I received "Cannot create a QPixmap when no GUI is being used" error. It seems that version 0.11.0_rc1 requires X to render opacity property.
That's why I tried the version pointed here - http://thelazylog.com/how-to-resolve-cannot-create-a-qpixmap-when-no-gui-is-being-used-when-running-wkhtmltopdf/ - 0.10.0_rc2
It works just fine on server without X 😄

For the latest (0.12.3) version I got this working with below code:

03_command:
command: yum install xz urw-fonts libXext openssl-devel libXrender
04_command:
command: wget http://download.gna.org/wkhtmltopdf/0.12/0.12.3/wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
05_command:
command: tar -xJf wkhtmltox-0.12.3_linux-generic-amd64.tar.xz
06_command:
command: cp wkhtmltox/bin/wkhtmltopdf /usr/local/bin/wkhtmltopdf
07_command:
command: cp wkhtmltox/bin/wkhtmltoimage /usr/local/bin/wkhtmltoimage

Forgive me not having proper YAML format but I wasn't able to format it.
