Clojurians Log v2

Hi, is anybody doing appengine development in clojure ? About to start a clojure gae project targeting the standard Java runtime. I've only built apps appengine with python. Having Clojure->Java makes it a bit harder to get my head around how things should work. Now trying out https://github.com/alpeware/lein-jaq & https://github.com/xlfe/clojure-app-engine

There seem to be a few projects out there for gae, but most of them seem old & not maintained 🙂

Jaq looks really nice for management & dev-server, but the repl flow seems to be missing. It xlfe/clojure-app-engine just fire a repl and then (start-it) 🙂

hi there.

We have done some.

We have 1 app deployed in app engine.

but we’re in App engine Flex

I’m more than happy to share our build scripts and dockerfile stuff with you…

But basically, what we do is to build an uberjar and use the openjdk jre (v8 at the moment)

our DockerFile looks like this:

FROM java:openjdk-8-jre

# Prepare the image.
ENV DEBIAN_FRONTEND noninteractive
RUN apt-get update && apt-get install -y -qq --no-install-recommends wget unzip python php5-mysql php5-cli php5-cgi openssh-client python-openssl && apt-get clean

# Install the Google Cloud SDK.
ENV HOME /
ENV CLOUDSDK_PYTHON_SITEPACKAGES 1
RUN wget <https://dl.google.com/dl/cloudsdk/channels/rapid/google-cloud-sdk.zip> &amp;&amp; unzip google-cloud-sdk.zip &amp;&amp; rm google-cloud-sdk.zip
RUN google-cloud-sdk/install.sh --usage-reporting=true --path-update=true --bash-completion=true --rc-path=/.bashrc


# Disable updater check for the whole installation.
# Users won't be bugged with notifications to update to the latest version of gcloud.
RUN google-cloud-sdk/bin/gcloud config set --installation component_manager/disable_update_check true

# Disable updater completely.
# Running `gcloud components update` doesn't really do anything in a union FS.
# Changes are lost on a subsequent run.
RUN sed -i -- 's/\"disable_updater\": false/\"disable_updater\": true/g' /google-cloud-sdk/lib/googlecloudsdk/core/config.json


RUN mkdir /.ssh
ENV PATH /google-cloud-sdk/bin:$PATH

ENV PORT 8080

EXPOSE 8080
COPY target/standalone.jar standalone.jar
CMD ["java", "-jar", "standalone.jar"]

@claudiu: ☝️

app.yaml looks like this:

# [START appyaml]
runtime: java
env: flex
service: fulliautomatix
manual_scaling:
  instances: 1

handlers:
- url: /.*
  script: this field is required, but ignored


# [END appyaml]

@domparry Thank you for sharing. Trying to see if I can get things rolling in the standard env. Mostly because of billing 😄 running a python website 1k visitors a day for free is nice, should be the same in java

Are you also using the datastore & tasks ? Trying to get my head around how the local dev work. So far seems like I have to make a war, unpack and run devserver on that build 🙂

I was thinking of trying to do the same, but had other priorities to worry about. Please share if you manage to get it going…

We are using tasks. It works super well.

I’m using this app to kick off cloud dataflow jobs…

nice :slightly_smiling_face: did you get the project with repl to work with _ah/admin ? :slightly_smiling_face:

I didn’t try to get the repl working for this, because you can’t really repl into a running dataflow pipeline

cool. I'm building a webapp. Standard stuff api + server side rendering. Repl really helps 🙂

Hi, @alpeware Thank you for open-sourcing jaq 🙂 Noticed there's an https://github.com/alpeware/jaq-example. Any chance the meetup demo was recorded ? 🙂
