Adjust graylog entrypoint.sh with curl

Hello Team,

I was trying to bring curl command to bring some properties enabled once graylog is up but its not working for me

I tried below thing
graylog() {

exec "${JAVA_HOME}/bin/java" \
${GRAYLOG_SERVER_JAVA_OPTS} \
-jar \
-Dlog4j.configurationFile="${GRAYLOG_HOME}/data/config/log4j2.xml" \
-Djava.library.path="${GRAYLOG_HOME}/lib/sigar/" \
-Dgraylog2.installation_source=docker \
"${GRAYLOG_HOME}/graylog.jar" \
server \
-f "${GRAYLOG_HOME}/data/config/graylog.conf"
}

**curl() {
curl something
}**

run() {
setup
graylog
**curl**
}

run

but its not working , then I tried below thing

graylog() {

exec "${JAVA_HOME}/bin/java" \
${GRAYLOG_SERVER_JAVA_OPTS} \
-jar \
-Dlog4j.configurationFile="${GRAYLOG_HOME}/data/config/log4j2.xml" \
-Djava.library.path="${GRAYLOG_HOME}/lib/sigar/" \
-Dgraylog2.installation_source=docker \
"${GRAYLOG_HOME}/graylog.jar" \
server \
-f "${GRAYLOG_HOME}/data/config/graylog.conf" &&
**curl something**
}

it works command gets executed but container keeps on restarting , even I tried below thing s

graylog() {

"${JAVA_HOME}/bin/java" \
${GRAYLOG_SERVER_JAVA_OPTS} \
-jar \
-Dlog4j.configurationFile="${GRAYLOG_HOME}/data/config/log4j2.xml" \
-Djava.library.path="${GRAYLOG_HOME}/lib/sigar/" \
-Dgraylog2.installation_source=docker \
"${GRAYLOG_HOME}/graylog.jar" \
server \
-f "${GRAYLOG_HOME}/data/config/graylog.conf" &&
**curl something**
exec "$@"
}
