Hi,
I was able to connect my IDE to Solr running on a container by using the
following command:
command: >
bash -c "solr start -c -f -a
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005;"
It starts SolrCloud ( -c ) and listens on foreground ( -f ) so you don't
need to resort to tail -f.
OTOH, I understand that you want to run the commands below after the
container is up and Solr is accepting connections:
wait-for-solr.sh;
solr create -c data_core -d /var/lib/solr/data_core;
IMHO, you could put those commands in a bash script (setup.sh in my
example) and start them first in background. Therefore, while the setup.sh
script is attempting to connect to Solr the server is starting in
foreground:
command: >
bash -c "./myscript.sh& exec solr start -c -f -a
-agentlib:jdwp=transport=dt_socket,server=y,suspend=n,address=5005; "
See that there's an 'exec' keyword between the script and the solr
launching command.
Best,
Edward
