I am trying to connect to mysql server running on host machine (localhost) from a spring app running inside a docker container
this is my Dockerfile
FROM openjdk:11
ADD build/libs/demo-0.0.1-SNAPSHOT.jar demo.jar
EXPOSE 8000
RUN mkdir -p tmp/scripts
RUN mkdir -p tmp/logs
ENTRYPOINT ["java","-jar","/demo.jar"]
I am using Docker desktop for mac v2.3.0.3 with engine version 19.03.8
This is may hikariCP datasource connection properties
spring.datasource.jdbcUrl=jdbc:mysql://**host.docker.internal:3306**/freshid
spring.datasource.username=sa
spring.datasource.password=test
When I build docker build -f Dockerfile -t demo . and run the image as docker run -p 8000:8000 demo
I get the following error on application start up
The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

I uninstalled and re-installed the docker (19.03.8) and it worked. The final connection string is jdbc:mysql://host.docker.internal:3306/db. This does not conclude any technical correctness but it worked. Thanks.
I would suggest a simple solution.
Step 1: Turboshooting: Try to run springboot appliction in you machine, outside container. If works fine, then there is no issue your application. (Make sure while testing locally you change your DB connection string from host.docker.internal to localhost)
Step 2: Please expose your DB port, that is 3306 by default in case of mysql when you run Docker Container with imperitive command
docker run -p 8000:8000 -p 3306:3306 demo
This should resolve your issue 😎😎

I have a Spring Boot + MySQL application which cannot start in docker environment (manually it runs with no errors, but I have to change the application.properties)
So first I launch the MySQL in docker with these command:
docker run -p 3307:3306 --name mysqldb -e MYSQL_ROOT_PASSWORD=root -e MYSQL_DATABASE=exp mysql
And here it is the docker containers list:
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
0cc5c690fb7e mysql "docker-entrypoint.s…" 30 seconds ago Up 30 seconds 33060/tcp, 0.0.0.0:3307->3306/tcp, :::3307->3306/tcp mysqldb
This is screenshot of server connection settings for the database
When the database is running, I launch the Spring app with following commands in terminal:
docker run -p 9090:8080 --name exp --net spring-net -e MYSQL_HOST=mysqldb -e MYSQL_USER=root -e MYSQL_PASSWORD=root -e MYSQL_PORT=3306 exp
As you can see, I used the docker network which is connected to mysqldb with following command docker network connect spring-net mysqldb
Here are the application.properies settings:
spring.jpa.properties.hibernate.dialect=org.hibernate.dialect.MySQL5Dialect
spring.jpa.hibernate.naming-strategy=org.hibernate.cfg.ImprovedNamingStrategy
spring.jpa.properties.hibernate.ddl-auto=update

spring.datasource.username=root
spring.datasource.password=root
spring.datasource.initialization-mode=always
spring.datasource.validationQuery=SELECT 1

spring.server.compression.enabled=true
spring.jpa.database-platform=org.hibernate.dialect.H2Dialect
spring.jpa.hibernate.ddl-auto=update
spring.jpa.properties.hibernate.format_sql=true
When I try to start this, the application cannot find the mysqldb, here is the error from console:
Caused by: java.net.UnknownHostException: mysqldb

However, when I change the spring.datasource.url inside application.properties to this:
spring.datasource.url=jdbc:mysql://localhost:3307/exp?verifyServerCertificate=true&useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
and build it it runs following exception:

I think it is too late to connect the mysql container to the same network as your spring container, so I would suggest you first create the network and use that in both of your containers.
$ docker network create my-network
Then you have to use the mysqldb container name and the inside port in your application.properties (because you are trying to connect from a container) like this:
spring.datasource.url=jdbc:mysql://mysqldb:3306/exp?verifyServerCertificate=true&useSSL=false&serverTimezone=UTC&useLegacyDatetimeCode=false
Recently, the stable version (1.6.2) of apache flink was released. I read this instruction. But when I run the following command:
./bin/flink run examples/streaming/SocketWindowWordCount.jar --port 9000
I get the following error:

I found this link:Flink program cannot submit when i follow flink-1.4's quickstart and use "./bin/flink run examples/streaming/SocketWindowWordCount.jar --port 9000". However, it didn't help. I tried with Flink 1.6.2 with Hadoop® 2.8 as well as Flink 1.5.5 with Hadoop® 2.8 on mac os and ubuntu. But I just got the same error.
Works fine for me. Only difference I can see is that I'm using the version of Flink without hadoop, but I doubt that's the issue.
java.net.ConnectException: Connection refused usually means that there is no service listening on port 9000. You should have netcat running on this port via
$ nc -l 9000
(see https://ci.apache.org/projects/flink/flink-docs-stable/quickstart/setup_quickstart.html#run-the-example). If netcat is running, and it's not working, maybe try another port? It might also help to check all the log files for additional clues.
I solved the annoying problem by reading the nc -h (in Linux):
connect to somewhere: nc [-options] hostname port[s] [ports] ...
listen for inbound: nc -l -p port [-options] [hostname] [port]
So for listening a port, -p is mandatory, and I tried the following command:
nc -l -p 9000
and It worked.
I have Ubuntu running as a virtual machine using Oracle VM. In this VM in run elasticsreach docker using this command:
sudo docker run -d --name elasticsearch -p 9200:9200 -p 9300:9300 elasticsearch
In Oracle VM machine network setting I added this port forwarding:
Host Guest
127.0.0.1:9200 --> 127.0.0.1:9200
127.0.0.1:9300 --> 127.0.0.1:9300
When I try to send http request using chrome to the address 127.0.0.1:9200 and 127.0.0.1:9300 I get a response with no problem.
When I try to connect using Java Client API I get this exception:

As you can see it connect successfully to 127.0.0.1:9300, but then it get the node ip (172.17.0.2) and of course the connection to it failed (There is no ping from my windows that run the VM to this ip).
I tried to disable the firewall and add this fort forwarding:
172.17.0.2:9300 --> 172.17.0.2:9300
or
172.17.0.2:9300 --> 10.0.0.15:9300
(10.0.0.15 is the ip of the VM)
but no success.
I understand the problem is in port forwarding, but how can I solve it?
I looked on this issue, but I don't find here an answer, and guess it another problem.
The problem is that Elasticsearch cluster is located on a different network which is the network Docker had created.
One way to solve it is using SSH tunneling on your local machine to that network and forward from local a port to remote 9300.
Here is an example on how how to define SSH tunneling and a sample code on how to connect to Elasticsearch using JAVA client API.

Exception connecting to localhost/9052. Reason: Connection refused.
stdout: Not connected to a cassandra instance.
Not connected to a cassandra instance.
I've tried altering the port and the localhost hostname to 127.0.0.1 and 0.0.0.0 but this makes no difference really.
I'm using java version "1.7.0_71"
Any ideas would be appreciated, thanks
The issue was cassandra trying to start on a hostname that was not in my /etc/hosts file.
I found which hostname by running /Users/xxx/dev/xxxx/build/cassandra/bin/cassandra -f which gave better output as to what the issue was.
I am running Titan 0.5.0 with Cassandra 2.0.8.
When I first ran my Java client with a local Titan-Cassandra I could connect to it. Now that I deployed the Titan-Cassandra remotely on a Debian Wheezy with dedicated user I have a "Connection refused exception" (see stack below). I can connect to Titan via Rexter on the remote server via http://my-domain.com:8182 and I can see my vertices and edges.
What is the changes to do on a local configuration (Java client and Titan on same machine) to make Titan with Cassandra and Elasticsearch run on a remote machine accessed by my Java client?
Java client code
private final URL titanConfiguration =TitanRepository.class.getResource("/conf/titan-cassandra.properties");
public TitanGraph load() {
return TitanFactory.open(titanConfiguration.getPath());
}

If Rexster runs on the same (remote) box and can connect, but you can't connect from your local machine, then it's most likely a Cassandra configuration issue. In cassandra.yaml set rpc_address to 0.0.0.0 (currently you've probably set it to 127.0.0.1), restart Cassandra and try to connect again.
