They are different tools for different purposes: php-cli is the standalone tool for running a PHP scripts in the same way you would run it from the command line: php somescript.php. It seems you can also use it to base other images from. This variant contains the PHP CLI tool with default mods. If you need a web server, this is probably not the image you ...

I do not believe that there is a way to set this as a global policy. However, there is a simple command you can run that will "prune" or remove your unused images. You will want to use docker image prune --filter [options] to achieve this. Check out the official documentation for information on how to best filter. As a best practice you should be tagging ...

With Docker following the Open Container Initiative, in the event that Docker were to disappear, people would still have access to images stored outside of Docker Hub. While there is not a public mirror of Docker Hub, you do have access to other registries that often store the official image. For example, if you were to pull the official Docker SQL Server ...

You can run the container in detached mode by passing -d or --detach with the run command: https://docs.docker.com/engine/reference/run/#detached-vs-foreground

you should minimize the Layers of an Image for following Reasons: first, you can only have (afaik) 127 Layers in an Image. second: yes, you should include severals Steps in a Single run because of the Copy-On-Write functionality: if you run: RUN dd if=/dev/zero of=output.dat bs=1M count=10 RUN rm -rf output.dat your image is still 10MB (plus some bytes ...

Those images are the docker build cache. You need this to be able to quickly rebuild similar images, and to avoid rebuilding unchanged layers which would result in resending those to remote registry servers and forcing servers to download those unchanged layers again. One important point on these layers: They do not consume any significant disk space You ...

The general design pattern is one container = one running service - see the initial comment at https://docs.docker.com/config/containers/multi-service_container/ Now, after spending about a year developing a multi-service application relying heavily on docker this is what works for me: Avoid creating files inside the container unless it is your storage ...

I don't know of a way to get the actual GCE VM images. But it's possible to export the images to GCS (as a tar.gz archive): If you need to move your Compute Engine boot disk data outside of your Compute Engine project, you can export a boot disk image to Cloud Storage as a tar.gz file. You can export a custom image as backup or for sharing by ...

From https://docs.docker.com/docker-hub/official_repos/ Docker, Inc. sponsors a dedicated team that is responsible for reviewing and publishing all content in the official repositories. This team works in collaboration with upstream software maintainers, security experts, and the broader Docker community. While it is preferable to have upstream software ...

Before giving the answer I'd like to clarify that S3 is meant for object storage, meaning that there's no file system involved and thus there are not "directories" per se. So, an "object" with the name "/avatars/user-123/xyz" might give you the impression that it's stored in the "/avatars/user-123" directory, but there's no directory involved, that's just a ...

When you download mariadb image, mysql client tool is only available inside container. It is not getting magically installed on your local - that is why you had to install mysql client app. Alternative way to connect to db without installing mysql app is to use docker exec and through this get to mysql tool available on container. So you would do something ...

As the documentation clearly states docker run command should be invoked as follows: docker run [OPTIONS] IMAGE[:TAG|@DIGEST] [COMMAND] [ARG...] so when you run docker run mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password Docker assumes -p 3306:3306 -e MYSQL_ROOT_PASSWORD=password is a command you want to run inside the container, not a list of options ...

One way to use curl inside the container will be to use a custom Dockerfile to build you postgrsql container. Just use the image: postgres:12-alpine as the base image of your Dockerfile and install curl in alpine with the following command : RUN apk --no-cache add curl

They are the same thing with different names. It's a general term.

Whoever created basex/basexhttp:latest does not seem to know Docker very well. They copied files necessary to a directory that was later configured as a volume, which means it can only be bound to an anonymous volume, otherwise files inside will be removed. They left source code inside the image, they used a single stage build with maven:3-jdk-8-alpine as ...

thought it was working because docker-compose build returned without errors. I've tried a few URL's, but can't quite tell what happened: root $ root $ docker-compose up Starting frappe_docker_erpnext-nginx_1 ... frappe_docker_mariadb_1 is up-to-date frappe_docker_redis-cache_1 is up-to-date Starting frappe_docker_traefik_1 ... frappe_docker_erpnext-...

Solution is to use exec as: root@doge:~# root@doge:~# docker run -ti -d --name basexhttp --publish 1984:1984 --publish 8984:8984 --volume "$(pwd)/basex/data":/srv/basex/data basex/basexhttp:latest 5699af1dc04aa9c78066222e4b0b8e5621aa2ab9dd2bd46bcd87c6a0377c1960 root@doge:~# root@doge:~# docker container list CONTAINER ID ...

You're attempting to create two different containers, each with the same name. Each time you execute docker run it will create a container, and you've named the containers the same with --name basexhttp. These names must be unique, even among stopped containers. To delete an unneeded container, you can stop and remove it with: docker container stop basexhttp ...

In my opinion, your real problem about this is getting incomplete data that didn't include image scanning, hardening and trusted registries. Here are some first directions: The well curated Official Docker Images on DockerHub You can setup trusted docker registries and setup docker clients to evaluate these based on content trust. If you are planning to ...

You might have better luck finding answers to your questions if you use the more standard term of "containerization". This article discusses containerization as well as some pros and cons you might want to consider.

So I ended up using this simple shell script docker images -q --filter "before=ecr.us-east-1.amazonaws.com/myapp:02e56bac4ee3f27a4d5670a6ac0d578e3dd5b2e5" | xargs docker rmi --force First you filter your images to list only those created before the latest one (you either know your recent tag or just use latest one) The you just remove those images with ...
