Access IQFeed datafeed through TCP (port 9100) or HTTP (port 8080);
This is an Alpine-docker container that runs wine/Xvfb/IQFeed and offer this as TCP/HTTP-endpoint.
Copy the iqfeed.env.example to iqfeed.env and configure the variables to match as supplied by IQFeed.

Next pull this project from hub.docker
docker pull mpdroog/docker-iqfeed:v1OR build it yourself with build.sh

LookupPort 9100 - Historical Data, Symbol Lookup, News Lookup, and Chains Lookup information
HTTP 8080 - Historical Data
The datapoints through HTTP are limited to MaxDatapoints(10.000). If you want a higher amount use the second example that reads minute-data using mode=chunked with CSV.
# Get 1 daily candle for MicroStrategy as JSON
$ curl "http://localhost:8080/ohlc?asset=MSTR&range=DAILY&datapoints=1"

Connection closed by foreign host.For all accepted commands by IQFeed have a look at http://www.iqfeed.net/dev/api/docs/HistoricalviaTCPIP.cfm
The TCP-server in this Docker container proxy's any commands to IQFeed (upstream). Because of this I've
adjusted the code to send an READY\r\n from the server instead of waiting for the client to initiate the connection.
(Motivation is that this way you can see why it failed)
The iqapi-tool is a combination of services allowing us to build layer on layer with precise control.
Layer1. Start xvfb
Layer2. Start wine64 iqfeed
Layer3. Start and listen on admin-conn (9300)
Layer4. Start and listen for your reqs (9100)
(i) When xvfb crashes it will respawn xvfb and only respawn iqfeed when xvfb is running again.
iqapi is a blocking-process that writes everything to stdout+stderr so Docker should offer all of that to your standard logging facility (probably journal on systemd env).
There is an IQFeed errorlog available in the container:
docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
.....
docker exec -it PUT_CONTAINER_ID_HERE /bin/sh
# Print current instance log
cat /home/wine/DTN/IQFeed/IQConnectLog.txt
# Print log of instance before it respawned
