Support alpine linux #50

thenewguy · 2020-04-03T18:24:27Z

Add installation support for Alpine linux. This would be very helpful when docker containers need to be used in a CI environment.

thenewguy · 2020-04-04T14:04:46Z

Below is an Alpine based docker image that will build and install the efs-utils via the deb builder. All good there. I have been using it for testing so it would need to be modified for your needs to do something suitable. It probably has some requirements that are not needed, but it is for a beanstalk deployment builder.

However, the start_watchdog function will need to be modified for Alpine support so that -o tls can be used

FROM docker:19.03-git
COPY domain.crt /usr/local/share/ca-certificates/domain.crt
RUN update-ca-certificates \
    && apk add --no-cache curl python2 python2-dev py2-pip gcc libffi-dev musl-dev openssl-dev make bash \
    && pip install awsebcli awscli \
    && python --version && pip freeze
RUN apk add --no-cache dpkg binutils nfs-utils stunnel openssl util-linux \
    && mkdir -p /tmp/efsutils \
    && cd /tmp/efsutils \
    && git clone https://github.com/aws/efs-utils . \
    && ./build-deb.sh \
    && dpkg --force-all -i ./build/amazon-efs-utils*.deb \
    && rm -Rf /tmp/efsutils
RUN sed -i '/#region = us-east-1/s/^#//' /etc/amazon/efs/efs-utils.conf && cat /etc/amazon/efs/efs-utils.conf
COPY . /eb

This image will let you mount like: mount -t efs ${EFS_FILE_SYSTEM_ID}:/ ${EFS_MOUNT_DIR}

It DOES NOT support mount -t efs -o tls ${EFS_FILE_SYSTEM_ID}:/ ${EFS_MOUNT_DIR} yet.

Thanks for the feedback. We’ll have someone take a look and post a more detailed response once we better understand the issue.

thenewguy · 2020-04-07T18:43:09Z

@lilferna the issue is that the two handled cases for init_system are not available for alpine. There are many simple ways to solve this. Will wait for your feedback

thenewguy · 2020-04-07T18:46:17Z

@lilferna for example, adding support for something like http://supervisord.org/ would let you support any distribution that can run python. So you could punt the problem.

@lilferna Any chance for an update?

thenewguy · 2020-05-17T14:19:03Z

I will do the work for you if you will just let me know it will be merged

Cappuccinuo · 2020-05-18T00:23:06Z

Hi @thenewguy ,

Sorry for the late reply. If you can submit a pull request, that will be great, we will review that once you submit one, thanks.

thenewguy · 2020-05-18T00:33:39Z

Do you have a preference on the init system used?

Cappuccinuo · 2020-05-18T13:02:18Z

What's the unrecognized init system of alpine linux container? I assume there should be a warning message in the log file, Could not start %s, unrecognized init system **?

If we use supervisor, the init system will be supervisord right?

thenewguy · 2020-05-18T13:36:50Z

There isn't one. I'd have to go back and check but I think it just parsed the shell. Would you be happy with attempting to fall back to supervisor if init system fails and supervisor is detected since it is cross platform?

Cappuccinuo · 2020-05-18T14:04:31Z

If 1. init system is not systemd or init, 2. supervisor is detected, 3. watchdog is not already started, then I think we can use supervisor to start the watchdog.

thenewguy · 2020-06-08T15:11:17Z

This is backlogged for me. Unfortunately a different direction was taken while waiting on approval of this issue. If anyone else is available to tackle the problem feel free

I'm running Alpine Linux as the OS for my EC2 instances. Here's the current patch I'm applying in order to get mount.efs to work...

I am not using this on alpine anymore but still got a notice. If you have a working solution you should submit it as a PR!

@Cappuccinuo

We're using the #136 patch to build efs-utils APK packages for Alpine Linux -- it'd be nice if this was brought into the mainline, someday.
