As per the Docker documentation, overlay network is automatically getting created when we initialise docker swarm. But we can not use that network for individual docker container which not part of swarm resource. So, we need to create overlay network with "–attachable" flag. I tried to create attachable overlay network but I am getting following ..

I’m using VS Code’s "Dev Container: Python3 & PostgreSQL" containers to do some development and, as support is built in, using git for version control. Problem is, I want to push code to a remote repo but git, which I believe is running in the container (that’s just how VS Code has set it up), ..
I’m trying to put springboot application packaged in .jar in docker container and use connection to database which is inside another docker container. When launching application from Idea (while db already running on docker container) everything works fine. However, it’s not working as intended when .jar is inside container, and returns next error: application | ..
I’m trying to dockerize with docker-compose a stack of clients and services to realize E2E tests in Continuous Integration. The stack (every component is shipped whit its Dockerfile) is composed by: a Cypress project (separated from the angular project) an Angular web application client a NodeJS authentication server a Spring Boot resource server a Oracle ..
It seems to me docker can’t really do this or isn’t suited for jt since there’s no easy way to do it. I’d appreciate any kdeas, suggestions, pointers, feedback. I want to set up a network topology using containers. It would be something like Machine A <— machine B <— machine C ^<— machine D ..
I have two Docker containers. Container One is named 5extraextranodes_plc1_1, and is run with docker-compose on a bridge network named test_net. Container 2 is built and run outside of docker-compose. In container 2, there is a Python3 script. Inside this Python3 script, I want to be able to look up the 5extraextranodes_plc1_1 container’s IP address. ..
What is the easiest way to compare IP addresses using Scapy (in Python3.6) and Docker? I have a piece of code that sniffs my Docker bridge network using Scapy sniff(). I want to look at each packet’s source IP address, and if it matches the IP address for my container named "plc1", do additional steps. ..
I’m developing a solution that makes Docker services accessible as subdomains on an NGINX instance. Docker’s embedded bridge networks allow sibling containers to be discovered by their names; I can resolve a container service-1 as http://service-1 using the pseudo-DNS system. However, I’m stuck as to actually discovering these peers within the network. I know that ..
I am experiencing a weird issue where docker cannot resolve one of my networks version: "3.5" services: nginx: container_name: nginx_al image: nginx:latest volumes: – ./ssl:/ssl/ – ./nginx.conf:/etc/nginx/nginx.conf:ro ports: – "80:80" – "443:443" – "8080:8080" depends_on: – keycloak – server – admin – client networks: – client – admin – backend – keycloak keycloak: container_name: keycloak_al ..
A problem with a Docker Container running NextJS application trying to access another Docker Container running a NestJS-API.
