![]() First, create the volume that Portainer Server will use to store its database. That is, if you want to create it, but are okay with the default settings, then there is no particular reason to specify the parameters. Both elements run as lightweight Docker containers on a Docker engine. ![]() By checking the version this is what I get: Matteos-MacBook-Pro-2:chateo matteo docker-compose -v docker-compose version 1.14.0, build c7bdf9e shouldnt it be 1.17 I dont get it. version: 3 volumes: jenkinshome: services: registry: image: registry:2 ports: - '5000:5000' jenkins: image: jenkins/jenkins ports: - '9090:8080' volumes: - jenkinshome. So I tried to update my docker running on MacOs, but its up to date. This question already has answers here : Docker: where is docker volume located for this compose file (2 answers) Closed 5 years ago. There is a tendency to accept these "empty" definitions for things like volumes and networks when you don't need to do anything other than define that a volume or network should exist. It looks to me something to do with an old version of docker-compose. "Empty" definitions in docker-compose.yml WARNING! This will remove all volumes not used by at least one container. ![]() That will give you this output, and you choose whether to continue pruning or not. Compose can also run in the background as a daemon when launched with the -d option: docker-compose up -d 7.2. "Name": "1c59d5b7e90e9173ca30a7fcb6b9183c3f5a37bd2505ca78ad77cf4062bd0465",Īs far as just ensuring that things are not left dangling, you can use the prune commands, in this case docker volume prune. If our file has a different name than the default one (docker-compose.yml), we can exploit the -f and file flags to specify an alternate file name: docker-compose -f custom-compose-file.yml start. You can find out exactly where the volume is stored on your system if you want to: $ docker inspect 1c59d5b7e90e9173ca30a7fcb6b9183c3f5a37bd2505ca78ad77cf4062bd0465 volumes: - type: bind <- not 'volume' source: /host/folder target: /container/folder/. Since youre mounting a host directory, you need to specify type: bind in the extended syntax. Local a3d54ec4582c3c7ad5a6172e1d4eed38cfb3e7d97df6d524a3edd544dc455917 The type: field says whether its a named volume, a bind mount, or a couple of other things. If you want to use a folder where you docker-compose is located, you can write. When you write admin-logs:C:/app/Logs, youre telling docker-compose to use a volume named admin-logs. In a docker-compose.yml file, users can define volumes and attach them to. You can use a relative path to the location of your docker-compose.yml file. You can get a list of volumes: $ docker volume ls Volumes are a way of preserving data created by and utilized by Docker containers. ![]() Volumes like this are internal to Docker and stored in the Docker store (which is usually all under /var/lib/docker). ![]()
