mysql2-lambda's Issues

SSL Support?

I am trying to use a PlanetScale database with my Ruby Lambda, and while I can run it locally and in docker, I get "SSL connection error: unknown error number" when running in Lambda.

  require 'active_record'
  require 'mysql2-lambda'
  require 'mysql2'
  ActiveRecord::Base.establish_connection(
    adapter: 'mysql2',
    database: 'xxx',
    username: 'xxx',
    host: 'xxx',
    password: 'xxx,
    sslverify: true,
    # ssl_mode: :verify_identity,
    # sslca: '/etc/ssl/cert.pem',
  )

    "errorMessage": "SSL connection error: unknown error number",
    "errorType": "Function<ActiveRecord::ConnectionNotEstablished>",
    "stackTrace": [

Ruby 2.7.5

The gem doesn't seem to work on ruby 2.7.5

Bundle installs all the gems, but when I try to require the gem, I get this error:

It worked with ruby 2.7.4, but AWS updated the base image with ruby 2.7.5

Here is my Dockerfile:

FROM public.ecr.aws/lambda/ruby:2.7

# Copy dependency management file
COPY lambda/Gemfile ${LAMBDA_TASK_ROOT}

# Install dependencies under LAMBDA_TASK_ROOT
ENV GEM_HOME=${LAMBDA_TASK_ROOT}/vendor/bundle
RUN bundle install
# Copy function code
COPY lambda ${LAMBDA_TASK_ROOT}

# Set the CMD to your handler (could also be done as a parameter override outside of the Dockerfile)
CMD [ "lambda_function.LambdaFunction::Handler.process" ]

The file is there

sh-4.2# ls -l /var/task/vendor/bundle/gems/mysql2-lambda-0.5.3.1/lib/mysql2/mysql2.so
-rwxr-xr-x 1 root root 5363112 Dec  1 15:08 /var/task/vendor/bundle/gems/mysql2-lambda-0.5.3.1/lib/mysql2/mysql2.so

but it doesn't seem to be a dynamic exec

sh-4.2# ldd /var/task/vendor/bundle/gems/mysql2-lambda-0.5.3.1/lib/mysql2/mysql2.so
        not a dynamic executable

external dependency on downloads.mysql.com

If https://downloads.mysql.com/archives/ goes away, the curl in the Dockerfile will fail, presenting a rather critical external dependency. Is this at all a concern?

Unable to get it working with serverless-ruby-layer

I am trying to use it with serverless-ruby-layer, ruby 7.2

getting following error

Error loading the 'mysql2' Active Record adapter. Missing a gem it depends on? Could not find 'mysql2' (~> 0.5) among 379 total gem(s)\nChecked in 'GEM_PATH=/opt/ruby/2.7.0:/var/runtime' , execute `gem env` for more information"
