I am trying to carry out some experiments with Docker, MongoDB, and mongo-express.
Here was what I did:
docker network create my-network
docker run -d -p 27017:27017 --network my-network --name my-mongo -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=pass mongo
docker run -d -p 8081:8081 --network my-network --name my-mongo-express -e ME_CONFIG_OPTIONS_EDITORTHEME="ambiance" -e ME_CONFIG_MONGODB_SERVER="my-mongo" -e ME_CONFIG_BASICAUTH_USERNAME="admin" -e ME_CONFIG_BASICAUTH_PASSWORD="pass" mongo-express
No error message was received apparently.
However, when I entered the address "localhost:8081" on Chrome, the page displayed an error message saying:
This page isn’t working
localhost didn’t send any data.
ERR_EMPTY_RESPONSE
How can I fix this?
You set the admin username and password on the database, but then you use the 'normal' user environment variables to try to log on. Instead of ME_CONFIG_BASICAUTH_USERNAME and ME_CONFIG_BASICAUTH_PASSWORD, you should use ME_CONFIG_MONGODB_ADMINUSERNAME and ME_CONFIG_MONGODB_ADMINPASSWORD, like this
docker run -d -p 8081:8081 --network my-network --name my-mongo-express -e ME_CONFIG_OPTIONS_EDITORTHEME="ambiance" -e ME_CONFIG_MONGODB_SERVER="my-mongo" -e ME_CONFIG_MONGODB_ADMINUSERNAME="admin" -e ME_CONFIG_MONGODB_ADMINPASSWORD="pass" mongo-express

I'm creating a mongo container using this command
docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --net mongo-network --name mongodb mongo
, then executing this command to see its logs docker logs mangodb
i'm getting this reult
i cant understand if mongodb is successfully created or not
After pulling run this commands
"docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network mongo "
for mongodb and this
"docker run -d -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net mongo-network --name mongo-express -e ME_CONFIG_MONGODB_SERVER=mongodb mongo-express"
for mongo express after opening the port in my localhost:8081 on server side it is showing that "Turn on admin in config.js to view server stats!" i'm kind of stuck here
Had the same problem. So i went and checked mongo-express-docker Github issue page. Someone raised a question there.
Apparently, mongo-express in docker latest release is 1.0.0-alpha, doesn't have server status, but 0.54.0 had it.
Try: docker pull mongo-express:0.54.0
And then remember to use mongo-express:0.54.0 for whatever you're doing later.
I tried adding a tag --restart always. It's working fine for me.
docker network create mongo-network
docker run -d -p 27017:27017 -e MONGO_INITDB_ROOT_USERNAME=admin -e MONGO_INITDB_ROOT_PASSWORD=password --name mongodb --net mongo-network --restart always mongo
docker run -d -p 8081:8081 -e ME_CONFIG_MONGODB_ADMINUSERNAME=admin -e ME_CONFIG_MONGODB_ADMINPASSWORD=password --net mongo-network --name mongo-express -e ME_CONFIG_MONGODB_SERVER=mongodb --restart always mongo-express
I launch a container running PostgreSQL with the command:
docker run -p 5432:5432 -d -it -e POSTGRES_USER='postgres' -e POSTGRES_PASSWORD='postgres' -e POSTGRES_DB='thingsboard' --name postgres postgres
Then, I launch ThingsBoard providing some environment variables to use the PostgreSQL database:
docker run -it -p 9090:9090 -p 1883:1883 -p 5683:5683/udp -v ~/.mytb-data:/data -v ~/.mytb-logs:/var/logs/thingsboard --name thingsboard --restart always -e SPRING_DATASOURCE_URL=jdbc:postgresql://<MY_LOCAL_IP>:5432/thingsboard -e SPRING_DATASOURCE_USERNAME=postgres -e SPRING_DATASOURCE_PASSWORD=postgres thingsboard/tb-postgres
where <MY_LOCAL_IP> is my IP address on the local network. I checked PostgreSQL, which actually binds to <MY_LOCAL_IP>:5432 (verified through PGAdmin).
The thingsboard container returns an error:
I expect ThingsBoard itself to create the tables in the thingsboard database, but it seems that it doesn't appen so. Any guess on the possible cause of this error? Thanks.
It seems that the problem is given by the volumes: mytb-data and mytb-logs have been created before and are not empty. The containers work as long as we launch thingsboard with:
docker run -it -p 9090:9090 -p 1883:1883 -p 5683:5683/udp --name thingsboard --restart always -e SPRING_DATASOURCE_URL=jdbc:postgresql://<MY_LOCAL_IP>:5432/thingsboard -e SPRING_DATASOURCE_USERNAME=postgres -e SPRING_DATASOURCE_PASSWORD=postgres thingsboard/tb-postgres
I am trying to install pgadmin4 using Docker in Ubuntu 18.04 LTS, but each time I create a container it crashes. Am I missing something in the below command
$ docker pull dpage/pgadmin4
$ docker run -p 80:80 \
-e 'PGADMIN_DEFAULT_EMAIL=atinesh.s#gmail.com' \
-e 'PGADMIN_DEFAULT_PASSWORD=admin' \
-d dpage/pgadmin4
Solved the issue with following command
$ docker run -p 80:80 \
-e PGADMIN_DEFAULT_EMAIL="atinesh.s#gmail.com" \
-e PGADMIN_DEFAULT_PASSWORD="admin" \
-d dpage/pgadmin4
Im getting errors trying to run my docker containers. I need the postgres and redis connected to my server application.
docker pull postgres
docker rm -f syda-postgres
docker run -p 30203:5432 --name syda-postgres -e POSTGRES_PASSWORD=password POSTGRES_USER=root POSTGRES_DB=syda postgres
docker pull redis
docker rm -f syda-inmemory
docker run -d -p 30204:6379 --name syda-inmemory redis redis-server --appendonly yes
docker pull docker.url.ee/syda/server:latest
docker rm -f syda-server
docker run -d -p 30202:8080 --name syda-server --link syda-postgres:postgres --link syda-inmemory:redis \docker.url.ee/syda/server:latest
This is the error im getting:
Error: No such container: syda-postgres
docker: invalid reference format: repository name must be lowercase.
See 'docker run --help'.
Error: No such container: syda-server
docker: Error response from daemon: could not get container for syda-postgres: No such container: syda-postgres.
See 'docker run --help'.
docker run -p 30203:5432 --name syda-postgres -e POSTGRES_PASSWORD=password POSTGRES_USER=root POSTGRES_DB=syda postgres
That tries to run a container from the image named POSTGRES_USER=root with the command/arguments to the entrypoint POSTGRES_DB=syda postgres. You need to pass the -e for each variable like:
docker run -p 30203:5432 --name syda-postgres \
-e POSTGRES_PASSWORD=password -e POSTGRES_USER=root -e POSTGRES_DB=syda \
postgres
Also, note that links are deprecated, you should use a shared network for communicating between containers. This is often done with a compose file. If you need to do it from a script, you could run:
docker pull postgres
docker pull redis
docker pull docker.url.ee/syda/server:latest
docker rm -f syda-postgres
docker rm -f syda-inmemory
docker rm -f syda-server
docker network rm syda-net
docker network create syda-net
docker run -p 30203:5432 --net syda-net --name syda-postgres \
-e POSTGRES_PASSWORD=password -e POSTGRES_USER=root -e POSTGRES_DB=syda \
postgres
docker run -d -p 30204:6379 --net syda-net --name syda-inmemory \
redis redis-server --appendonly yes
docker run -d -p 30202:8080 --net syda-net --name syda-server \
docker.url.ee/syda/server:latest
