Current Behavior

I am trying to migrate from LSIO Unifi Controller on Unraid to LSIO UNA.

I have installed MongoDB official docker with the following docker run-
docker run
-d
--name='unifi-network-application'
--net='bridge'
-e TZ="America/New_York"
-e HOST_OS="Unraid"
-e HOST_HOSTNAME="Brunnhilde"
-e HOST_CONTAINERNAME="unifi-network-application"
-e 'MONGO_USER'='unifi'
-e 'MONGO_PASS'='password'
-e 'MONGO_HOST'='unifi-db'
-e 'MONGO_PORT'='27017'
-e 'MONGO_DBNAME'='unifi'
-e 'MEM_LIMIT'='1024'
-e 'MEM_STARTUP'='1024'
-e 'MONGO_TLS'=''
-e 'MONGO_AUTHSOURCE'=''
-e 'PUID'='99'

When I try to start the UNA docker the log shows that the host db is unreachable. I suspect that my MongoDB docker is missing a variable for the host db but I'm unable to find the proper variable.

Thanks for opening your first issue here! Be sure to follow the relevant issue templates, or risk having this issue marked as invalid.

You need to put them on a user defined bridge network. The default bridge does not allow container to container name resolution

Thanks. I’ll try that.

This didn't work. I created a custom docker network with the command
docker network create unifi
Edited both dockers to use Custom: unifi. Still getting the same error in UNA.

h3ndrk · 2023-10-27T09:11:22Z

Same error here. I used a docker-compose.yml with the MongoDB and UniFi with depends_on: but it seems that the MongoDB is seen as ready too early and Docker Compose already starts the UniFi service. If starting the services manually after each other with some delay, it works for me.

This doesn’t work for me. The mongodb docker has been running for several days but I still get an error when trying to start UNA.

rsauget · 2023-10-29T17:59:39Z

Same issue here. If I docker exec into the container to run a wget $MONGO_HOST:$MONGO_PORT it works, really confusing

rsauget · 2023-10-29T18:05:49Z

Actually, I see in the init script here

docker-unifi-network-application/root/etc/s6-overlay/s6-rc.d/init-unifi-network-application-config/run

Line 26 in d571bd1

elif ! nc -w1 "${MONGO_HOST}" ${MONGO_PORT} >/dev/null 2>&1; then

that it runs nc, but I can't find that binary in the image 🤔

thespad · 2023-10-29T18:20:31Z

$ docker exec -it unifi bash
root@6bf6ca9fe9cf:/usr/lib/unifi# which nc
/usr/bin/nc

niki-on-github · 2023-10-29T18:59:49Z

Same issue. After using healthcheck in for mongo + depends_on the Host can be resolved. I think we should solve the actual problem in init script. Here we need to check with a loop for the host to become available and not block with sleep infinity forever. Why was this issue closed without resolving the problem?

j0nnymoe · 2023-10-29T19:08:09Z

It was closed because the original issue was the user didn't have the containers on the same custom docker bridge so they couldn't talk with each other.

It was closed because the original issue was the user didn't have the containers on the same custom docker bridge so they couldn't talk with each other.

While that was part of the problem, fixing it didn’t resolve the issue. I was able to resolve it using the MongoDB init js file instead of the init variables in the MongoDB docker though. So I guess the original issue is resolved.

Hi all having the same issue. *** Defined MONGO_HOST unifi-db is not reachable, cannot proceed. *** Below is my docker compose file. I browsed all the issues back and forth and could not get into any working config for me on my Synology NAS DS-720+ x86-64bit. Controller works just fine, trying to migrate.
