How to add module to Wildfly using CLI

I’m trying to create a Wildfly docker image with a postgres datasource.

When I build the dockerfile it always fails with Permission Denied when I try to install the postgres module.

  • In docker run, how to set multi-value in --ulimit
  • How to remove file/folder from Docker container without starting this container
  • docker-machine, docker-compose and google cloud
  • How to use docker run with a Meteor image?
  • Two apt-get arguments to a docker run command doesn't work
  • cannot connect to docker on RemoteServer using Ansible
  • My dockerfile looks look this:

    FROM wildflyext/wildfly-camel
    RUN /opt/jboss/wildfly/bin/ admin admin --silent
    ADD postgresql-9.4-1201.jdbc41.jar /tmp/
    ADD /tmp/
    ADD batch.cli /tmp/
    RUN /tmp/

    Which calls the following:

    function wait_for_wildfly() {
      until `$JBOSS_CLI -c "ls /deployment" &> /dev/null`; do
        sleep 10
    echo "==> Starting WildFly..."
    $JBOSS_HOME/bin/$ -c $JBOSS_CONFIG > /dev/null &
    echo "==> Waiting..."
    echo "==> Executing..."
    $JBOSS_CLI -c --file=`dirname "$0"`/batch.cli  --connect
    echo "==> Shutting down WildFly..."
    if [ "$JBOSS_MODE" = "standalone" ]; then
      $JBOSS_CLI -c ":shutdown"
      $JBOSS_CLI -c "/host=*:shutdown"


    module add --name=org.postgresql --resources=/tmp/postgresql-9.4-1201.jdbc41.jar --dependencies=javax.api,javax.transaction.api

    The output when building is:

    ==> Starting WildFly…
    ==> Waiting…
    ==> Executing… Failed to locate the file on the filesystem copying /tmp/postgresql-9.4-1201.jdbc41.jar to
    /tmp/postgresql-9.4-1201.jdbc41.jar (Permission denied)

    What permissions are required, and where do I set the permission(s)?


  • Docker: Npm install very slow in Ubuntu host
  • Openstack Nova docker implement security group
  • Docker with WebHDFS
  • Where can I create images from? Locally at all? (Docker remote API)
  • Docker Data Volume Container - Can I share across swarm
  • JHipster docker image from DockerHub is not working

    It seems the JAR file is not readable by the jboss user (the user comming from parent image). The postgresql-9.4-1201.jdbc41.jar is added under the root user – find details in this GitHub discussion.

    You could

    • either add permissions to JAR file before adding it to the image
    • or add permissions to JAR file in the image after the adding
    • or change ownership of the file in the image

    The simplest solution could be the first one. The other 2 solutions need also switching user to root (USER root in dockerfile) and then back to jboss.

    Here a advice : make a cli file like this :

    module add --name=sqlserver.jdbc --resources=@INSTALL_FOLDER@/libext/jtds-1.3.1.jar --dependencies=javax.api,javax.transaction.api

    replace @VAR@ by our own value… and It should work!
    Be caution than JBOSS/Wildfly 10 think relatively for jar –resources by default but wildfly 8 think absolute path this could make you weird ! 😉


    Docker will be the best open platform for developers and sysadmins to build, ship, and run distributed applications.
