A lot of other tomcat docker images exist, but the only support development or not use the newest version or bundle an open jdk. We want build a nicer one. Send us your missing features!\n\n**Goals**\n* use minimal ubuntu and java8 base images (work in progress)\n* inject libs and wars as volumes (data container)\n* deploy the manager app and generate password at start\n* clean up installation and remove examples and unused `*.bat`, .. files.\n* squash footprint and clean up build artefacts\n* use a nicer access log pattern :-)\n* use a cleanup server.xml without comments\n * use separate executor\n * setup HTTP (8080) and AJP (8009) connectors and expose ports\n * currently not support APR Connectors or configure other then standard NIO\n* reuse existing cool ideas from other nice guys. Many thanks;)\n\nYou can deploy your own webapps and tomcat extended library with local volumens or better with a docker data container.\n\n![Apache Tomcat 8 docker image design](design-tomcat8-images.png)\n\n## Found the tomcat docker images\n\nCurrently the apache tomcat8 images are available as automatic docker hub build and a squash version.\n\n* [docker hub build](https://registry.hub.docker.com/u/rossbachp/apache-tomcat8/)\n* [optimized squash build](https://registry.hub.docker.com/u/rossbachp/tomcat8/) (s. build.sh)\n\n## Dependencies\n\n* [ubuntu](https://registry.hub.docker.com/u/_ubuntu)\n* [Dockerbox java8 image: rossbachp/java8 source ](https://github.com/rossbachp/dockerbox/tree/master/docker-images/java8)\n* [rossbachp/java8 images ](https://registry.hub.docker.com/u/rossbachp/java8)\n* [Apache Tomcat 8 Download ](https://archive.apache.org/dist/tomcat/tomcat-8)\n* [squashing-docker article](http://jasonwilder.com/blog/2014/08/19/squashing-docker-images/)\n\n## Installation\n\n1. Install [Docker](https://www.docker.com/).\n2. Download [rossbachp/java8](https://registry.hub.docker.com/u/rossbachp/java8): `docker pull rossbachp/java8`\n3. Download [rossbachp/tomcat8](https://registry.hub.docker.com/u/rossbachp/tomcat8): `docker pull rossbachp/tomcat8` or [rossbachp/apache-tomcat8](https://registry.hub.docker.com/u/rossbachp/apache-tomcat8): `docker pull rossbachp/apache-tomcat8` or\n\n## Usage\n\n docker run -it --rm -P rossbachp/apache-tomcat8\n docker run -it --rm -P rossbachp/tomcat8\n\n### Run _tomcat8_ with a sample _hello world_\n\n mkdir -p hello\n cd hello\n echo \"Hello Docker Tomcat World\" >index.jsp\n jar -cf ../hello.war .\n cd ..\n docker run --name=tomcat8 -d -p 8080:8080 -v `pwd`:/webapps rossbachp/tomcat8\n curl http://127.0.0.1:8080/hello/index.html\n\n### Run _tomcat8_ with a sample _hello world_ at a data container\n\n mkdir -p hello\n cd hello\n echo \"Hello Docker Tomcat World\" >index.jsp\n jar -cf ../hello.war .\n cd ..\n vi Dockerfile\n\n**Dockerfile**\n\n FROM busybox\n MAINTAINER Peter Rossbach \n\n RUN mkdir /webapps\n ADD hello.war /webapps/hello.war\n\n VOLUME [\"/webapps\"]\n\n CMD /bin/sh\n\n**Running**\n\n docker build -t=\"rossbachp/hello-app\".\n docker run -it --name=hello-app rossbach/hello-app ls /webapps\n docker run --name=tomcat8 -d -p 8080:8080 --volumes-from hello-app rossbachp/tomcat8\n curl http://127.0.0.1:8080/hello/index.html\n\n**deploy with your system parameters**\n\n docker run -it --rm --env CATALINA_OPTS=\"-Ddb.user=admin -Ddb.password=secret\" -v `pwd`/webapps:/webapps -v `pwd`/libs:/libs rossbachp/tomcat8\n\n**use your own JVM_ROUTE**\n\n docker run -it --rm --env TOMCAT_JVM_ROUTE=tomcat79 -p 7980:8080 -p 7909:8009 -v `pwd`/webapps:/webapps rossbachp/tomcat8\n\n**stop tomcat**\n\n docker stop --time=10 tomcat8\n\n -
