###Run DR simulators as docker container

  1. Build docker container with docker build -t drsim_common:latest .
  2. Run the container docker-compose up
  3. For specific behavior of of the simulators, add arguments to the command entries in the docker-compose.yml. For example command: node dmaapDR.js --tc no_publish . (No argument will assume '--tc normal'). Run node dmaapDR.js --printtc and node dmaapDR-redir.js --printtc for details or see further below for the list of possible arg to the simulator

###Run DR simulators and all other simulators as one group See the README in the 'simulator-group' dir.

###Run DR simulators from cmd line

  1. install nodejs
  2. install npm Make sure that you run these commands in the application directory "dr-sim"
  3. npm install express
  4. npm install argparse
  5. node dmaapDR.js #keep it in the foreground, see below for a list for arg to the simulator
  6. node dmaapDR_redir.js #keep it in the foreground, see below for a list for arg to the simulator

###Arg to control the behavior of the simulators

DR

--tc tc_normal                      Normal case, query response based on published files. Publish respond with ok/redirect depending on if file is published or not.</br>
--tc tc_none_published              Query respond 'ok'. Publish respond with redirect.</br>
--tc tc_all_published               Query respond with filename. Publish respond with 'ok'.</br>
--tc tc_10p_no_response             10% % no response for query and publish. Otherwise normal case.</br>
--tc tc_10first_no_response         10 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_100first_no_response        100 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_all_delay_1s                All responses delayed 1s (both query and publish).</br>
--tc tc_all_delay_10s               All responses delayed 10s (both query and publish).</br>
--tc tc_10p_delay_10s               10% of responses delayed 10s, (both query and publish).</br>
--tc tc_10p_error_response          10% error response for query and publish. Otherwise normal case.</br>
--tc tc_10first_error_response      10 first queries and requests gives no response for query and publish. Otherwise normal case.</br>
--tc tc_100first_error_response     100 first queries and requests gives no response for query and publish. Otherwise normal case.</br>

DR Redirect

--tc_normal                         Normal case, all files publish and DR updated.</br>
--tc_no_publish                     Ok response but no files published.</br>
--tc_10p_no_response                10% % no response (file not published).</br>
--tc_10first_no_response            10 first requests give no response (files not published).</br>
--tc_100first_no_response           100 first requests give no response (files not published).</br>
--tc_all_delay_1s                   All responses delayed 1s, normal publish.</br>
--tc_all_delay_10s                  All responses delayed 10s, normal publish.</br>
--tc_10p_delay_10s                  10% of responses delayed 10s, normal publish.</br>
--tc_10p_error_response             10% error response (file not published).</br>
--tc_10first_error_response         10 first requests give error response (file not published).</br>
--tc_100first_error_response        100 first requests give error responses (file not published).</br>

###Needed environment

DR

DRR_SIM_IP     Set to host name of the DR Redirect simulator "drsim_redir" if running the simulators in a docker private network. Otherwise to "localhost"
DR_FEEDS       A comma separated list of configured feednames and filetypes. Example "1:A,2:B:C" - Feed 1 for filenames beginning with A and feed2 for filenames beginning with B or C.

DRR_SIM_IP is needed for the redirected publish request to be redirected to the DR redirect server.

DR Redirect (DRR for short)

DR_SIM_IP      Set to host name of the DR simulator "drsim" if running the simulators in a docker private network. Otherwise to "localhost"
DR_REDIR_FEEDS Same contentd as DR_FEEDS for DR.

The DR Redirect server send callback to DR server to update the list of successfully published files. When running as container (using an ip address from the dfc_net docker network) the env shall be set to 'drsim'. . When running the servers from command line, set the env variable DR_SIM_IP=localhost
