Php: New Relic

[Rudis1261]

Hi Guys,

Sorry that this isn't really an issue, but rather a question.

How do you monitor your PHP application with New Relic in a docker container? Do you have a separate container and link it to all your PHP containers?

Or do you apt-get install it and set the configuration for it?

Cheers,

[polds]

We build it into the container:

# Install New Relic
RUN apt-get update 
RUN apt-get -yqq install wget
RUN apt-get -yqq install python-setuptools
RUN easy_install pip
RUN mkdir -p /opt/newrelic
WORKDIR /opt/newrelic
RUN wget -r -nd --no-parent -Alinux.tar.gz \
    http://download.newrelic.com/php_agent/release/ >/dev/null 2>&1 \
    && tar -xzf newrelic-php*.tar.gz --strip=1
ENV NR_INSTALL_SILENT true
ENV NR_INSTALL_KEY NEWRELIC_LICENSE_KEY_HERE
RUN bash newrelic-install install
WORKDIR /
RUN pip install newrelic-plugin-agent
RUN mkdir -p /var/log/newrelic
RUN mkdir -p /var/run/newrelic

Awesome thank you for the info, I will give it a try.

[Rudis1261]

The only change I made it to copy the license in, thank you so much!

# Install New Relic

RUN apt-get -yqq install wget
RUN apt-get -yqq install python-setuptools

    && tar -xzf newrelic-php*.tar.gz --strip=1
COPY config/newrelic.license /opt/newrelic/
ENV NR_INSTALL_SILENT true
RUN export NR_INSTALL_KEY=`cat /opt/newrelic/newrelic.license`

What base image are you using?

I'm trying to do this with php:5.6.18-fpm and I'm having this error: ALERT: oops, unknown child (6) exited with code 0. Please open a bug report (https://bugs.php.net).

We use several different versions of php+apache

[Rudis1261]

Mine doesn't seem to be working just yet. Do you mind sharing your Dockerfile to show us how you implemented this? Then again I am using PHP7 with this. Do you think that would be an issue?

[polds]

I haven't checked if it will work with PHP7. That'd be a question for NewRelic on whether or not they support 7 yet.

Here is our full mostly un-changed dockerfile. While it targets PHP 5.4 we use very similar iterations of this in other PHP 5.6 and lower configurations:

Thank you so much for sharing! I will have to fiddle when I have some spare time

[joserobleda]

My issue was with the newrelic.ini file. I overrides any previous global .ini directive, so my .ini license key was overridden by an empty string.

Closing, given that this isn't an issue specific to the PHP image. I recommend contacting New Relic for help with their solutions, if necessary. :+1:
