By default, it will run the Grails app using the `prod run-app` (or `prod run-war` for Grails 2) directive which is the most optimized way of running Grails for production environments. However, you can easily change the default behaviour for your specific uses (see the _Changing Behaviour_ section for more details on this). 4 | 5 | ## Technologies / Versions Used 6 | - Grails 3.2.8 (by default; all versions from `2.0.0` up to `3.2.8` can be specified) 7 | - Java JDK 7+ (for Grails 2) or 8+ (for Grails 3) 8 | - Tomcat 7+ (for Grails 2) or 8+ (for Grails 3) 9 | 10 | ## Running Using Defaults ## 11 | By default, the container will start inside Grails interactive mode. From here, you can run the app by simply typing `run-app` or execute any other valid Grails commands you may want to. 12 | 13 | Use the following command to run on default mode (remember to ALWAYS specify your app folder in the `-v` command): 14 | 15 | `docker run --rm -v /path/to/your/project:/app:rw -p 80:8080 --name grails mozart/grails` 16 | 17 | > Note: This command will run the Grails container using the latest stable version of Grails 3. 18 | 19 | This default behavior can be altered by using the _tag_ modifier for specifying the Grails image version (see the _Image Tag_ version), by modifying the command when running the image (see the _Run Command_ version) or by editing the default environment variables (see the _Environment Variables_ section). 20 | 21 | ## Changing Behavior 22 | You can change the default behavior of the image by either changing some environment variables or executing a command rather than entering the default Grails interactive mode. 23 | 24 | ### Image Tag / Version 25 | You can change the default behaviour of the image when building and running it by specifying a different Grails image version using the _tag_ (e.g.:`{repository}/{imageName}:{tag}`) modifier at the end of the image identifier (e.g.: `docker run --rm -v /path/to/your/project:/app:rw -p 80:8080 --name grails mozart/grails:2`) 26 | 27 | ### Environment Variables 28 | The image contains the following customizable Grails related environment variables that can be changed inside the image's Dockerfile. 29 | 30 | - `GRAILS_VERSION`: Specifies the version of Grails to download (default: `3.2.8`; min: `2.0.0`; max: `3.2.8`). 31 | 32 | > **IMPORTANT:** When using the `GRAILS_VERSION` env var to specify a version less than `3.0.0` you MUST use the image version tag with a value of `2` (e.g.: mozart/grails:2). If not, image building will fail! 33 | 34 | ### Run Command 35 | You can execute a different Grails command rather than the interactive mode that is run by default, by specifying the command after the `mozart/grails` image name in the following form: ` {grails-command}`. For example: 36 | 37 | `docker run --rm -v /path/to/your/project:/app:rw -p 80:8080 --name grails mozart/grails:3 run-app` 38 | 39 | ## Building the Image 40 | You can build the image by yourself by executing: 41 | 42 | `docker build https://raw.githubusercontent.com/mozart-analytics/grails-docker/master/grails-3/Dockerfile` 43 | 44 | Or by downloading directly from the registry: 45 | 46 | `docker pull mozart-analytics/grails:{version|latest}` 47 | 48 | ## Extra: How to use for your Grails apps 49 | You can also leverage the use of this image for your internal apps if you want more freedom of customization and speed of initialization. To do this: 50 | 51 | 1. Create a Dockerfile for your app. 52 | 2. Use this image as the `FROM:` image of your app's Dockerfile. 53 | 3. Put your app's Dockerfile on the root of the app's folder. 54 | 4. Build your image using your own custom Dockerfile. 55 | 56 | An example of a Dockerfile for a Grails-Hello-World app could be: 57 | 58 | ### For Grails 3: 59 | ``` 60 | FROM mozart/grails:3 61 | MAINTAINER Manuel Ortiz Bey 62 | 63 | # Copy App files 64 | COPY . /app 65 | 66 | # Run Grails dependency-report command to pre-download dependencies but not 67 | # create unnecessary build files or artifacts. 68 | RUN grails dependency-report 69 | 70 | # Set Default Behavior 71 | ENTRYPOINT ["grails"] 72 | CMD ["run"] 73 | ``` 74 | 75 | ### For Grails 2: 76 | ``` 77 | FROM mozart/grails:2 78 | MAINTAINER Manuel Ortiz Bey 79 | 80 | # Copy App files 81 | COPY . /app 82 | 83 | # Run Grails refresh-dependencies command to 84 | # pre-download dependencies but not create 85 | # unnecessary build files or artifacts. 86 | RUN grails refresh-dependencies 87 | 88 | # Set Default Behavior 89 | ENTRYPOINT ["grails"] 90 | CMD ["run-app"] 91 | ``` 92 | 93 | Then build your Docker image by executing: 94 | 95 | `docker build -t "{repo-name}/Grails-Hello-World" .` 96 | 97 | And finally run your app as a Docker container by executing: 98 | 99 | `docker run -it -p 8080:8080 {repo-name}/Grails-Hello-World` 100 | 101 | ## References 102 | - More info about [phusion/baseimage](https://github.com/phusion/baseimage-docker). 103 | - More info about [Grails](https://grails.org/). 104 | 105 | ## Credits ## 106 | This image was inspired by the [niaquinto/grails](https://registry.hub.docker.com/u/niaquinto/grails/) image available in the Docker Registry Hub. 107 | -------------------------------------------------------------------------------- /grails-2/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM java:7 2 | MAINTAINER Manuel Ortiz Bey 3 | 4 | # Set customizable env vars defaults. 5 | # Set Grails version (max version for this Docker image is: 2.5.3). 6 | ENV GRAILS_VERSION 2.5.3 7 | 8 | # Install Grails 9 | WORKDIR /usr/lib/jvm 10 | RUN wget https://github.com/grails/grails-core/releases/download/v$GRAILS_VERSION/grails-$GRAILS_VERSION.zip && \ 11 | unzip grails-$GRAILS_VERSION.zip && \ 12 | rm -rf grails-$GRAILS_VERSION.zip && \ 13 | ln -s grails-$GRAILS_VERSION grails 14 | 15 | # Setup Grails path. 16 | ENV GRAILS_HOME /usr/lib/jvm/grails 17 | ENV PATH $GRAILS_HOME/bin:$PATH 18 | 19 | # Create App Directory 20 | RUN mkdir /app 21 | 22 | # Set Workdir 23 | WORKDIR /app 24 | 25 | # Set Default Behavior 26 | ENTRYPOINT ["grails"] 27 | -------------------------------------------------------------------------------- /grails-3/Dockerfile: -------------------------------------------------------------------------------- 1 | FROM java:8 2 | MAINTAINER Manuel Ortiz Bey 3 | 4 | # Set customizable env vars defaults. 5 | # Set Grails version (default: 3.2.8; min: 3.0.0; max: 3.2.8). 6 | ENV GRAILS_VERSION 3.2.8 7 | 8 | # Install Grails 9 | WORKDIR /usr/lib/jvm 10 | RUN wget https://github.com/grails/grails-core/releases/download/v$GRAILS_VERSION/grails-$GRAILS_VERSION.zip && \ 11 | unzip grails-$GRAILS_VERSION.zip && \ 12 | rm -rf grails-$GRAILS_VERSION.zip && \ 13 | ln -s grails-$GRAILS_VERSION grails 14 | 15 | # Setup Grails path. 16 | ENV GRAILS_HOME /usr/lib/jvm/grails 17 | ENV PATH $GRAILS_HOME/bin:$PATH 18 | 19 | # Create App Directory 20 | RUN mkdir /app 21 | 22 | # Set Workdir 23 | WORKDIR /app 24 | 25 | # Set Default Behavior 26 | ENTRYPOINT ["grails"] 27 | --------------------------------------------------------------------------------
