I want to run a crontab job on elastic search docker image
here is my docker file
[FROM docker.elastic.co/elasticsearch/elasticsearch:6.6.0
ENV PATH=$PATH:/usr/share/elasticsearch/bin
RUN yum -y update
RUN yum -y install crontabs
RUN echo -e "root\nelasticsearch" > /etc/cron.allow
RUN echo "" >> /etc/cron.allow
RUN chmod -R 644 /etc/cron.d
RUN cat /etc/cron.allow
RUN chown -R elasticsearch /etc/cron.d
RUN chmod -R 755 /etc/cron.d
RUN chown -R elasticsearch /var/spool/cron
RUN chmod -R 744 /var/spool/cron
RUN chown -R elasticsearch /etc/crontab
RUN chmod -R 744 /etc/crontab
RUN chown -R elasticsearch /etc/cron.d
RUN chmod -R 744 /etc/cron.d
COPY ./purge.sh /usr/share/elasticsearch
RUN ls -l /etc/crontab
RUN ls -l /etc/cron.d
RUN touch /usr/share/elasticsearch/cron.log
ADD ./cron /etc/cron.d/cron_test
RUN chmod 0644 /etc/cron.d/cron_test
RUN cd /etc/cron.d && cat cron_test
RUN chown -R elasticsearch /etc/cron.d/cron_test
RUN ls -l /etc/cron.d/cron_test
#This will add it to the cron table (crontab -e)
RUN crontab /etc/cron.d/cron_test
RUN crontab -l
RUN cd /var/spool/cron && ls
USER elasticsearch
ENTRYPOINT elasticsearch
CMD crond start && pgrep cron && tail -f && tail -f /usr/share/elasticsearch/cron.log
EXPOSE 9200 9300](http://)
after running this docker file and executing the container
in this step in docker file
RUN cd /var/spool/cron && ls
it's showing only root , but how can i get elasticsearch user in it ?
my cron file present locally
*/1 * * * * echo "Hello world" >> /usr/share/elasticsearch/cron.log
*/1 * * * * elasticsearch /usr/share/elasticsearch/purge.sh
my purge.sh file
curl -XPOST "http://localhost:9200/hydro_dashboard_index/_delete_by_query" -H 'Content-Type: application/json' -d'
{
"query": {
"range" : {
"query_service_entry_time" : {
"lt" : "now-14d"
}
}
}
}'
