By default creating a new docker container also creates a virtual network that separates the docker network environment from the host network environment (somewhat). This allows one to easily spin up multiple containers which might all listen on the same port (e.g. 80), but in a way that can be mapped to unique ports on … Read more
You should first start and enable docker in systemctl systemctl start docker systemctl enable docker
I’m using the mongodb 3.4 official docker image. Since the mongod doesn’t read a config file by default, this is how I start the mongod service: docker run -d –name mongodb-test -p 37017:27017 \ -v /home/sa/data/mongod.conf:/etc/mongod.conf \ -v /home/sa/data/db:/data/db mongo –config /etc/mongod.conf removing -d will show you the initialization of the container Using a docker-compose.yml: … Read more
Building on top of the answer by Joepreludian, focusing on docker-compose: You can use the user: and volumes: options in the compose file. For example: my-service: image: ubuntu:latest user: ${MY_UID}:${MY_GID} volumes: – /etc/passwd:/etc/passwd:ro – /etc/group:/etc/group:ro and define these variables where you are starting your compose: MY_UID=”$(id -u)” MY_GID=”$(id -g)” docker-compose up
Finally I found the way to fix. I have to deploy ingress Nginx by command: kubectl apply -f https://raw.githubusercontent.com/kubernetes/ingress-nginx/controller-v0.41.2/deploy/static/provider/cloud/deploy.yaml (Follows the instruction at https://kubernetes.github.io/ingress-nginx/deploy/#docker-for-mac. It works just fine for Docker for Windows) Now I can access http://ingress.local successfully.
I was hitting a similar problem trying to run Chromium headless in an Alpine Docker container, and apparently so are many other (e.g., here, here). The –no-sandbox option is a straightforward workaround but obviously a poor security practice. What worked for me was setting a custom seccomp.

Use only one ‘RUN’ statement. It’s a best practice as it will reduce the size taken by your image. This is how you can pass an argument to docker build. Dockerfile: … ARG NEW COPY ./compose/local/django/new.sh /new.sh COPY ./compose/local/django/start.sh /start.sh RUN if [ “$NEW” = “True” ]; then \ sed -i ‘s/\r//’ /new.sh && \ … Read more
I think the correct answer is from Aliases can be defined as part of the network declaration for a service. See aliases in Compose file reference for more details on that. – King Chung Huang Apr 24 ’17 at 15:18 here is the example from the doc version: ‘2’ services: web: build: ./web networks: – … Read more
You need to install the tzdata package and then set the enviroment variable TZ to a timezone. (List with all the timezones) FROM alpine:latest RUN apk add –no-cache tzdata ENV TZ=Europe/Copenhagen Output $ docker run –rm alpine date Tue Aug 31 09:52:08 UTC 2021 $ docker run –rm myimage date Tue Aug 31 11:52:13 CEST … Read more
I had the same issue in Dockerfile, then I used ARG DEBIAN_FRONTEND=noninteractive after base image and it works for me: Example Dockerfile: FROM ubuntu ARG DEBIAN_FRONTEND=noninteractive
