    though... that only works for direct deps. hmmm.

    Does anyone here have any experience injecting NPM_TOKEN into docker build using --build-args?
    I'd rather not hardcode my NPM_TOKEN in the build-args or the docker file
    I opened an issue about it on the lambci repo, I think it's an easy fix.
    feel free to ping me if I can help with it
    yesterday lambci started to throw weird errors when using gcc. my build cmd looks like this: . ~/init/gcc && npm install && npm test. output is
    $ . ~/init/gcc && npm install && npm run test
    Installing GCC 4.8.5...
    ++ curl -sSL https://lambci.s3.amazonaws.com/binaries/gcc-4.8.5.tgz
    ++ tar -xz -C /tmp
    ++ set +x
    GCC setup complete
    /bin/bash: line 1:    33 Segmentation fault      (core dumped) npm install
    Build #1 failed: Command ". ~/init/gcc && npm install && npm run test" failed with code 139
    if i remove . ~/init/gcc part, then build will succeed
    does anyone know whats wrong? :(

    How are you guys accessing secrets from the Docker container? I am particularly interested in getting the AWS keys
    I updated the Docker image to expect those as parameters on runbuild.sh, and updated the Lambda function to pass those env vars in the dockerBuild function
    I am hosting the revised image locally and redeployed the Lambda function. However ecs doesn't output any logs, so I might have messed up something. Wondering if there is an easier approach (other than hardcoding on lambci.json under the Docker configs)
    I just want to deploy whatever I build and test to S3... can't do on Lambda only because hit the disk size limit
    Michael Hart
    @stenio123 the ECS container will be running under an IAM Role already
    If you're using the aws-sdk for example, it will just get the credentials automatically
    @interisti that seg fault error should be fixed now – it was due to updates on the Lambda system that they did without warning. Let me know if it works for you now or not
    Stenio Ferreira
    @mhart this is the Dockerfile.test in my repo
    FROM mhart/alpine-node:6
    RUN apk update && \
        apk upgrade && \
        apk add \
            util-linux \
            pciutils \
            usbutils \
            coreutils \
            binutils \
            findutils \
            grep \
            curl \
            bash \
    RUN apk add \
            python \
            py-pip \
            && \
        pip install --upgrade awscli
    WORKDIR /tmp/lambci/build
    USER root
    # Build node_modules
    ADD  package.json /buildserver/
    RUN cd /buildserver && npm install
    # Now add the rest, the above layers will be cached if package.json doesn't change
    ADD . /tmp/lambci/build
    # Move npm modules over
    RUN rm -rf /tmp/lambci/build/server/node_modules && mv /buildserver/node_modules /tmp/lambci/build/server/
    RUN  cd /tmp/lambci/build && ./lambci.sh
    and in lambci.sh I have a bash script that tests and builds the code. The final step if to call an aws s3 sync... which is why I need the credentials
    Michael Hart
    I'm not sure what all the buildserver stuff is? Is this running on ECS and being triggered by Lambda?
    Stenio Ferreira
    yes. It is just because the files in my repo are not in the root directory, they are inside a "server" directory
    It builds fine, the only problem is I cant deploy to s3 because I dont have access to the credentials. Not sure how to rely on the IAM role for that
    When I ran this from Lambda (no Docker), it worked because the credentials are available as env variables. But I hit the 500mb limit. And in Docker the secret env vars are not passed
    Michael Hart
    the ec2 server should be running with an iam role – any time you use the aws sdk (and cli) on that server, it should pull the credentials for that iam role from the ec2 metadata
    so you'll just need to give that role access to whatever s3 bucket you need
    If you're using the CloudFormation template, you can just update the permissions from there – and update your stack: https://github.com/lambci/ecs/blob/master/cluster.template#L97-L137
    Stenio Ferreira
    @mhart OMG you are right lol. I got caught up in other errors and thought that was the problem. I think now I know what is wrong, and it is not the lack of AWS credentials. Thank you!
    Stenio Ferreira
    @mhart I am trying to understand what controls the constraints of how many concurrent deployments are possible when using lambci/ecs.
    On the CloudFormation template, the InstanceType parameter will determine the disk space/available computing power.
    How about the AutoScalingGroup properties? Do the defaults mean that only 1 build can be run at the same time? If I change that do I also need to change the CreationPolicy.ResourceSignal?
    Another thing is I have run into a "Thin pool" error, which went away once I cleaned the old Docker images. How do you deal with that, do you have a cron job on the ECS instance host that does the cleanup regularly?
    Stenio Ferreira
    The ECS agent supposedly should do the cleanup since it is version 1.14.1, however the problem only goes away once I run docker rmi $(docker images --filter "dangling=true" -q --no-trunc)
    I believe it is because I am building the Dockerfile.test everytime. I have seen that lambci/ecs runs build followed by run, but it is not clear to me how to pass a shell script to the run stage. Maybe if I could leverage $LAMBCI_DOCKER_RUN_ARGS?
    @mhart we removed that gcc step, cause dynalite now downloads the prebuilt image.
    Craig Steinberger
    Anyone interested in a PR that would help with deployments of lambci off of your own S3 buckets, rather than the public ones? It seems to be some parameterization in the publish.sh script, plus a step to create the buckets in the first place.
    Rohit Verma
    Is there any gitlab support or poc of that, has someone tried that?
    Amrit Gill
    New to lambci and wanted to know if it would be possible to pull lambda src from git, zip it and push it to an s3 bucket??? If so can I use the the lambci installation CFN template or would I have to customize it?
    Benjamin Baldivia
    Having a bit of trouble just getting started with this. I attempted to use "launch stack" as well as a few different ways (all really used same template though) and I get an error on "Custom::ConfigUpdater" every time. It looks like at the point in time "Custom::ConfigUpdater" is run the ConfigTable is not created yet. I adjusted the template and added "DependsOn: ["ConfigTable"]" for "ConfigUpdater" but the result of this was a completely different error: " Failed to create resource. User: arn:aws:sts::837930595040:assumed-role/lambci-private-LambdaExecution-LR33W5LBSV98/lambci-private-build is not authorized to perform: iam:PassRole on resource: arn:aws:iam::837930595040:role/lambci-private-SnsFailures-1Q43HAMIVMMR5" . I am honestly not very familiar with CloudFormation and all the config options that seem to be available. Is nobody else having this issue with this stack?
    Benjamin Baldivia
    T-T last message here from ~5 months ago... hopefully someone is still around?
    Michael Hart
    @Goblinlordx I haven't heard of anyone having this problem – what region are you launching it in?
    Benjamin Baldivia
    N. Virginia
    Benjamin Baldivia
    The error where the ConfigTable doesn't exist seems to not be happening now (with provided template) but it was definitely happening before =/
    Benjamin Baldivia
    still getting the error about PassRole permission though
    Benjamin Baldivia
    Fixed with your update~ Thanks @mhart

    Hi there everyone!
    Just wanted to ask a question. Is there a way to run lambCI builds manually
    for eg: I want run every night not on github web hook trigger
    Cory Mawhorter

    mhart continues to already-do-things-a-year-ago that i've just now thought about.

    i have a slow lambda fn that i'm thinking about moving off of lambda. but i'd like to avoid refactoring bc it's just a test and i think the reason for the move is temporary.

    is anyone aware of something that'd let me ship an existing lambda function using ecs? https://github.com/lambci/ecs seems like a good start, but that's purpose-built for lambci. maybe there is something out there for just this purpose?

    my goal is to continue building for lambda and as needed, move functions off lambda into ecs or back.

    actually... thinking more about this. vpc support in lambda is god-awful. this would be a workaround for that too until aws gets their house in order
    also efs. lol.

    Is there a more relevant chat medium for this project? Things seem dated in here.

    Hi @ianfixes – what's up?
