海外TECH	DEV Community	How to Use Docker Copy Command	https://dev.to/refine/how-to-use-docker-copy-command-216g	How to Use Docker Copy CommandAuthor Muhammad Khabbab IntroductionWe will discuss how to copy files in Docker using the docker copy command The docker cp command is a powerful command through which you can move files between your host file system and your Docker containers It works with both files and directories Steps we ll cover How to copy files in DockerHow docker copy command worksDifference between Copy and Add commandLimitations of Copy commandWhen should you use Docker copy How to copy files in DockerCopying important files and directories is an essential part of container building There are three ways to copy files in Docker docker CP command Dockerfile COPY command Using volume mountsToday we will discuss the docker cp command in detail We will also touch upon the COPY command in Dockerfile Let s start with the docker cp command first docker cp is a powerful command through which you can move files between your host file system and your Docker containers It works with both files and directories The cp command is the quickest way to copy files to and from docker container The cp command is very similar to the unix “cp command The basic syntax of the command is as follows docker cp lt src gt lt dest gt If you are running from the windows prompt then you need to mention the container name ID as part of the source Let s try one example The docker ps command will display the running containers Note the ID of the running container you want the files to copied to In above example the container ID is “aabd If you have opened the terminal CLI for a specific container then no need to mention the container ID Now let s find the files in the container through basic ls command The below command will copy the file app js from container to host file system in the folder D DockerCopy Note the container ID is mentioned in the source Instead of ID you can mention container name as well See the example below Just reverse the command and you can copy the file from host file system to the container The below example will copy a text file named “tocopy txt from host file system to the container To verify the successfully copy run the ls command in the container terminal You can see the file copied to container You can use the same command to copy not just single file but whole folder as well Note that the docker cp command assumes that container path is relative to the container s root directory Also the cp command will work regardless of container is running or stopped There are only two optional arguments for this command a Archive mode It preserves all uid gid information of the files to be copied L Always follow symbolic links in SRCYou can also use the docker cp command to copy files between two containers Just use the container name or ID in the source and destination paths  Copy through DockerfileLet s discuss how to copy files through dockerfile copy command The basic purpose of Dockerfile is to build Docker image which is then converted into Docker containers Dockerfiles can contain different commands one of which is COPY The COPY command allows us to copy a file or folder from the host system into the docker image The copied files become a part of every container that is created from that docker image The syntax is same as the cp command discussed above COPY lt source gt lt destination gt The below example will copy index html to the container to replace the default index html file …COPY index html var www html…If you build the docker image and run the container you will see the file will be copied Note that the COPY command cannot be used copy files between your host and a running container The sole purpose of COPY command is to add files in the docker image during the construction process Building a side project Meet the headless React based solution to build sleek CRUD applications refine expertly combines cutting edge technologies under a robust architecture so you don t have to spend time researching and evaluating solutions Try refine to rapidly build your next CRUD project whether it s an admin panel dashboard internal tool or storefront How docker copy command worksThe docker cp command is used to copy files to from your docker container to the host file system This command works even if the container is not running As Docker uses layers for storing images when you run the container Docker creates another layer on top of the existing layer The new layer contains all the changes done inside the container Note that it is not a data volume like a file system or a directory that we can mount directly to a docker container The data inside the container is managed by the storage driver Data is present inside the block level of the parent image of the container and this is where the cp command is executed Container is actually a snapshot of the image so it does not have the block but it has a pointer to the block on the nearest parent image where it is actually residing It reads the respective block from there and copies it upon execution of docker cp command Difference between Copy and Add commandThe ADD command has been there even before the cp command Although the cp command essentially performs the same function i e copying files and folders to a docker container However there are a few additional features in the Add command You can mention a URL as source The command will download the files from the URL and will copy them to the destination ADD destination folderThe above command will download all files from the source folder and will copy them to the destination folder of the container You can mention a compressed file in the source and it will decompress the contents and then copy them to the destination ADD source file gzip destination folderThe above example will extract the contents of a local zip file to the destination folder Note that you cannot mention a URL of a compressed file as a source the compressed file must be from the local file system This technique will stop creating an additional image layer and will save space too However in spite of all the extra features provided by ADD command Docker discourages its use because of safety reasons Docker suggests using only the cp command if copying a local file If you want to download and copy files from the internet then it suggests using the curl command with a RUN command The only recommended use of ADD is to extract the local tar file into the image as shown in below example ADD rootfs tar xz Limitations of Copy commandDespite of all he usefulness of Docker cp command it has certain limitations as below You cannot use it to copy files between two containers You will need to multi stage it by copying files from container to a host file system and then copying from the host file system to container You cannot use it to download files from a URL and then copy them Files must be present on the local file system You cannot copy certain system files such as resources under proc sys dev tmpfs etc When should you use Docker copyFollowing are some of the common use cases for the docker copy command You can copy any important file from inside a docker container to the host file system which will allow you to create a custom docker image the way you want it E g you can run the official Nginx docker image and then use the COPY command to copy the Nginx configuration file to the host file systemdocker cp is very useful when debugging containers or when working in a non production environment If you have to manually inject a temporary configuration file or extract a buried log it can be extremely helpful Using docker cp is more convenient and faster than rebuilding the entire image every time you update the code	2023-01-02 14:38:13
