Meteor Up Docker and Graphicsmagick

问题:

I'm looking for how to install Graphicsmagick at Meteor Up Docker.

I found this solution (Access binaries inside docker) but I couldn't make work, where do I put those lines at start.sh?

meteorDockerId=docker ps | grep meteorhacks/meteord:base | awk '{print $1}'
docker exec $meteorDockerId apt-get install graphicsmagick -y

That's my start.sh:

#!/bin/bash

APPNAME=instagatas
APP_PATH=/opt/$APPNAME
BUNDLE_PATH=$APP_PATH/current
ENV_FILE=$APP_PATH/config/env.list
PORT=80
USE_LOCAL_MONGO=0

# remove previous version of the app, if exists
docker rm -f $APPNAME

# remove frontend container if exists
docker rm -f $APPNAME-frontend

set -e
docker pull meteorhacks/meteord:base

if [ "$USE_LOCAL_MONGO" == "1" ]; then
  docker run \
    -d \
    --restart=always \
    --publish=$PORT:80 \
    --volume=$BUNDLE_PATH:/bundle \
    --env-file=$ENV_FILE \
    --link=mongodb:mongodb \
    --hostname="$HOSTNAME-$APPNAME" \
    --env=MONGO_URL=mongodb://mongodb:27017/$APPNAME \
    --name=$APPNAME \
    meteorhacks/meteord:base
else
  docker run \
    -d \
    --restart=always \
    --publish=$PORT:80 \
    --volume=$BUNDLE_PATH:/bundle \
    --hostname="$HOSTNAME-$APPNAME" \
    --env-file=$ENV_FILE \
    --name=$APPNAME \
    meteorhacks/meteord:base
fi


  docker pull meteorhacks/mup-frontend-server:latest
  docker run \
    -d \
    --restart=always \
    --volume=/opt/$APPNAME/config/bundle.crt:/bundle.crt \
    --volume=/opt/$APPNAME/config/private.key:/private.key \
    --link=$APPNAME:backend \
    --publish=443:443 \
    --name=$APPNAME-frontend \
    meteorhacks/mup-frontend-server /start.sh

Re-installing the graphicsmagick package every time you re-start the containers seems like a hack I wouldn't want to do.

If you're modifying the start script already, might as well use a Dockerfile:

FROM meteorhacks/meteord:base
RUN apt-get install graphicsmagick -y

Then modify start.sh template to build a new docker image with graphicsmagick, tag it and use that image instead:

see: https://gist.github.com/so0k/7d4be21c5e2d9abd3743/revisions

EDIT: Where to put Dockerfile?

start.sh template is copied to /opt/<appName>/config/, currently the Dockerfile would need to be in that same directory (/opt/<appName>/config/Dockerfile)

see Linux init Task

Alternatively, you can specify specific Dockerfile with the -f flag for the docker build

Or your third option is to pipe Dockerfile to docker build using a here document

I've updated the start.sh gist, we no longer pull the meteord:base image and build it instead:

docker build -t meteorhacks/meteord:app - << EOF
FROM meteorhacks/meteord:base
RUN apt-get install graphicsmagick -y
EOF

The docker build will run every time, but as long as the requirements aren't changing, docker will use the docker images it cached.

The development Version of Meteor Up at Kadirahq allows specification of a custom Docker Image in the config file (mup.js).

MeteorD-Images with Graphicsmagick installed are available on Docker Hub.

This got me a working deployment (Meteor 1.3.2.4, Meter Up 309cefb, Node v5.4.1):

mup.js:

module.exports = {
  …
  meteor: {
    dockerImage: 'ianmartorell/meteord-graphicsmagick',
    …
  },
};

I couldn't get the docker image that @hobbyhobbit mentioned to work, so I figured out how to write one that uses abernix/meteord:base and then has graphicsmagick installed. Very simple, but it seems to be working for me on Meteor 1.4.1.1

I just did this in my mup.js file

docker: {
  image: "joshjoe/meteor-graphicsmagick",
},

This was a huge pain to get working, so I'd be happy to help anyone who is struggling with this.

If the if statement successes, you should be able to see a running container corresponding to the image you are grepping. In my opinion you can add the two lines after the fi to obtain the environment variable.

回答5:

Build an image for get things right, but you can do temporary:

docker exec -it MeteorAppName apt-get install imagemagick -y

docker restart MeteorAppName

Check imagemagick: docker exec -it MeteorAppName convert -version

回答6:

Why don't you add the following package meteor add cfs:graphicsmagick https://atmospherejs.com/cfs/graphicsmagick

It tries to make sure Graphicsmagick is available. It worked for my use case i think it will work with docker too.
