pipeline memory limit - elasticsearch exceeded memory limit.



I am trying to run my functionnal tests in our bitbucket pipeline with elasticsearch an mysql as services.

But everytime, the pipeline launches, I get this error : elasticsearch exceeded memory limit.

Here is the content of my bitbucket-pipelines.yml : 


image:  php:7.1.1
  size: 2x
    - step:
          - composer
          - apt-get update && apt-get install -y unzip
          - curl -sS https://getcomposer.org/installer | php -- --install-dir=/usr/local/bin --filename=composer
          - composer install
          - bin/bootstrap
          - ./vendor/bin/simple-phpunit
          - elasticsearch
          - database
      image: elasticsearch:alpine
      image: mysql


I would be very gratefull of some help or some pointers.

Thx in advance,

The following configuration works for me

image: redis:4.0
memory: 512
image: elasticsearch:5.6
ES_JAVA_OPTS: '-Xms512m -Xmx512m'

I'm having memory issues as well. A pipeline that worked last Friday hits the memory limit. I even added the `2x` option but it still hits the memory limit.

The build should be pretty similar to each other but all of a sudden a 2x memory is not enough?

For me, it feels like the pipeline can not even build the elasticsearch docker image !!

I'm having a similar issue with an instance of the "microsoft/mssql-server-linux" SQL Server service.

It looks like the additional memory options don't apply to services, they're only shared with the pipelines, so when I start my pipeline, the mouseover on the log tabs in pipelines shows:

  • Build 7GB
  • mssql - 1GB

I can't see any obvious way to re-balance this for my needs.


You guys found a way to solve this or will I have to install my own CI tool ?

I got around it for now using a jvm.options file for elastic to limit the memory. I created a new dockerfile that was based on the elastic image we need, added in a jvm.options file with:


This keeps it under the 1GB service size.

They've recently added service size limitations that presumably you could just bump your elastic container to 1.5 or so (https://confluence.atlassian.com/bitbucket/use-services-and-databases-in-bitbucket-pipelines-874786688.html#UseservicesanddatabasesinBitbucketPipelines-Definingaservicewithcustomresourcelimits) but I can't get it to work.

If I follow their example with a "memory: 1536m" the online validator tool says it's expecting an integer, but if I put an integer it ignores it. Perhaps it's so new that their documentation is ahead of their implementation so maybe you'll have luck in the next days/weeks.
