hello, no i don’t use official jboss images..
i use a custom image build by me ..
on my dockerfile there is nothing related to env variables .. is on my entry
point script where i read em and do some substitutions in jboss config files
before launching jboss process .. that part works ok
but after that reading them from our java app does not work , their value is
null, .. and starting that same docker image in a docker standalone engine ,
and passing the same variables, works ok ..
my docker file is simple
FROM debian
RUN apt-get update -y
RUN apt-get install -y vim
RUN apt-get install -y sudo
USER root
COPY jboss.tar.gz / ( custom jboss tar.gz )
COPY jboss-as.conf /etc/init.d
COPY jboss-as /etc/init.d
RUN useradd -ms /bin/bash jbossadmin
RUN chmod +x /etc/init.d/jboss-as && chown jbossadmin: /etc/init.d/jboss-as
RUN cd / && tar xvfz jboss.tar.gz && rm jboss.tar.gz && chown -R jbossadmin:
/opt
RUN /opt/jboss/jboss-as/bin/add-user.sh admin Developer#2015 --silent
EXPOSE 8080
ENTRYPOINT ["/etc/init.d/jboss-as", "start”]
and in my entry point script i just do some replaces before starting jboss.
for example ( i have ASYNC_POOL word in the value entry of the xml inside the
jboss.tar.gz i use, so it get replaced ok )
sed -i -e 's/ASYNC_POOL/'"$ASYNC_POOL"'/g'
/opt/jboss/jboss-as/standalone/configuration/standalone.xml
and in my RC i set it as follows :
"env": [
{
"name”:"ASYNC_POOL",
"value”:"300"
},
etc etc
that works like a charm, but all this variables are NULL when recovering them
from my java app.
best regards
