Debian/Ubuntu

# Applicare Agent configuration
RUN apt-get update \
&& apt-get install -y curl unzip \
&& rm -rf /var/lib/apt/lists/*
RUN mkdir /usr/local/ApplicareSingleAgentLinux
WORKDIR /usr/local/ApplicareSingleAgentLinux
RUN curl CONTROLLER_PROTOCOL://CONTROLLER_IP:CONTROLLER_PORT/applicare/standalone?filename=ApplicareSingleAgentLinux >ApplicareSingleAgentLinux.zip
RUN unzip ApplicareSingleAgentLinux.zip
RUN ["rm", "-frv", "/usr/local/ApplicareSingleAgentLinux/ApplicareSingleAgentLinux.zip"]
RUN chmod -R 755 /usr/local/ApplicareSingleAgentLinux
ENV JAVA_OPTS="-noverify -Dserver.name=SERVER_NAME -javaagent:/usr/local/ApplicareSingleAgentLinux/applicare-aspects.jar=verbosity=0,logfile=false,norestart-intellitrace=false -Darcturus_home=/usr/local/ApplicareSingleAgentLinux -Djava.library.path=.;/usr/local/ApplicareSingleAgentLinux/bin -Dlogback.configurationFile=/usr/local/ApplicareSingleAgentLinux/logback/logback.xml"

Replace the following values in the above script

CONTROLLER_PROTOCOL -> http (or) https

CONTROLLER_IP -> Applicare Controller IP

CONTROLLER_PORT -> Applicare Controller Port
