Here is the my compose file definition
cli:
container_name: cli
image: hyperledger/fabric-tools:$IMAGE_TAG
tty: true
stdin_open: true
environment:
- GOPATH=/opt/gopath
working_dir: /opt/gopath/src/github.com/hyperledger/fabric/peer
command: /bin/bash
volumes:
- ./chaincode/:/opt/gopath/src/github.com/chaincode
- ./crypto-config:/opt/gopath/src/github.com/hyperledger/fabric/peer/crypto/
- ./artifacts:/opt/gopath/src/github.com/hyperledger/fabric/peer/channel-artifacts
I want the local folder chaincode sync with the container path /opt/gopath/src/github.com/chaincode
For that i've tried this command
docker run -v ./chaincode/:/opt/gopath/src/github.com/chaincode hyperledger/fabric-tools
docker run -i -t -volumes-from hyperledger/fabric-tools bash
But this still gives empty directory in the container

due to hardware problem, I had to replace my small home server with a new one.
Several self-hosted services with Docker were running on the server for which I tried to backup the volumes following the instructions on the official Docker website and those present in this YouTube video and in this cheat-sheet. Now, following the same documentation, I am trying to restore the backups but without success. The first one I'm trying for is a stack for Nginx Proxy Manager built with Docker compose with this docker-compose.yaml file:
version: "3.6"
services:
app:
image: jc21/nginx-proxy-manager:latest
restart: always
ports:
- "80:80"
- "443:443"
- "81:81"
environment:
DB_MYSQL_HOST: "db"
DB_MYSQL_PORT: 3306
DB_MYSQL_NAME: "db_name"
DB_MYSQL_USER: "db_user"
DB_MYSQL_PASSWORD: "db_password"
volumes:
- data:/data
- ./letsencrypt:/etc/letsencrypt
depends_on:
- db
db:
image: jc21/mariadb-aria:latest
restart: always
environment:
MYSQL_DATABASE: "db_name"
MYSQL_ROOT_PASSWORD: "root_password"
MYSQL_USER: "db_user"
MYSQL_PASSWORD: "db_password"
volumes:
- db:/var/lib/mysql
volumes:
db:
data:
After starting the stack with docker compose up -d command I'm trying to restore db and data volumes with:
docker run --rm --volumes-from nginx-proxy-manager-db-1 -v $(pwd):/backup ubuntu bash -c "cd / && tar xvf /backup/nginx-proxy-manager_db_20220717-082200.tar --strip 1"
docker run --rm --volumes-from nginx-proxy-manager-app-1 -v $(pwd):/backup ubuntu bash -c "cd / && tar xvf /backup/nginx-proxy-manager_data_20220717-082200.tar --strip 1"
What's wrong?
I have an issue with gitlab runner using docker:dind service.
I'm trying to run a docker-compose file with simple volume on a job, here the job :
test_e2e:
image: tmaier/docker-compose
stage: test
services:
- docker:dind
variables:
GIT_STRATEGY: none
GIT_CHECKOUT: "false"
DOCKER_DRIVER: overlay2
before_script:
- ls
script:
- cp .env.dist .env
- docker-compose -f docker-compose.yml -f docker-compose-ci.yml up -d
The job start normally but a container in docker-compose-ci.yml doesn't seem to mount the volume as specified in it, here docker-compose-ci.yml
version: '3.3'
services:
wait_app:
image: dadarek/wait-for-dependencies
networks:
- internal
depends_on:
- traefik
- webapp
command: webapp:3000
cypress:
# the Docker image to use from https://github.com/cypress-io/cypress-docker-images
image: "cypress/included:6.5.0"
networks:
- internal
depends_on:
- traefik
- webapp
- api
- mysql
- redis
environment:
# pass base url to test pointing at the web application
- CYPRESS_baseUrl=http://app.localhost:3000
working_dir: /cypress
volumes:
- ./cypress/:/cypress
Here if I make an "docker exec app_cypress_1 sh -c "ls -al" || 1" of /cypress folder inside the container cypress, I will have nothing even though I do have files in there on the host.
But I tried on a different version of the runner 13.7.0 instead of 13.5.0, and it work as expected.
Where could be the issue ? Is it the gitlab runner are maybe there is another parameter that I can change to make it work ?
Thank you
I have just started to learn Docker.
I have tried to run jenkins in my docker.
I have tried the commands:
docker run jenkins ,
docker run jenkins:latest
But showing the error in the docker interactive shell:
C:\Program Files\Docker Toolbox\docker.exe: Error response from daemon: manifest for jenkins:latest not found: manifest unknown: manifest unknown.
You can run the container by using the command
docker run -p 8080:8080 -p 50000:50000 jenkins/jenkins:lts
The documentation page is pretty good.
I would use a docker-compose file to
mount a volume for home to make it persistent
(in order to look into the build workspace you need to attach another container to it)
control the version programmatically
add docker client or other utilities installed later
add 'fixed' agents
docker compose file:
version: '3.5'
services:
jenkins-server:
build: ./JenkinsServer
container_name: jenkins
restart: always
environment:
JAVA_OPTS: "-Xmx1024m"
ports:
- "50000:50000"
- "8080:8080"
networks:
jenkins:
aliases:
- jenkins
volumes:
- jenkins-data:/var/jenkins_home
networks:
jenkins:
external: true
volumes:
jenkins-data:
external: true
dockerfile for server:
FROM jenkins/jenkins:2.263.2-lts
USER root
I am trying to make sure my docker work or not in my Jenkins,
I am running Jenkins in docker and it was running but when I check in Jenkins Pipeline, it said docker: not found
here is my docker-compose.yml
version: '3.7'
services:
jenkins:
image: jenkinsci/blueocean:latest
user: root
privileged: true
restart: always
ports:
- 8080:8080
volumes:
- ./jenkins_home:/var/jenkins_home
- /var/run/docker.sock:/var/run/docker.sock
- /usr/bin/docker:/usr/bin/docker
registry:
image: registry
container_name: registry
restart: always
ports:
- 5000:5000
then I run sudo docker-compose up -d
then the Jenkins is running,
can I know why the docker not found ? is my docker-compose wrong ?
You do not need to bind - /usr/bin/docker:/usr/bin/docker, as - /var/run/docker.sock:/var/run/docker.sock is engough to interact with host docker. you should not bind executable with docker container
remove this from the compose file and it should work.
- /usr/bin/docker:/usr/bin/docker
I need to be able fork a process. As i understand it i need to set the security-opt. I have tried doing this with docker command and it works fine. However when i do this in a docker-compose file it seem to do nothing, maybe I'm not using compose right.
Docker
docker run --security-opt=seccomp:unconfined <id> dlv debug --listen=:2345 --headless --log ./cmd/main.go
Docker-compose
Setup
docker-compose.yml
networks:
backend:
services:
example:
build: .
security_opt:
- seccomp:unconfined
networks:
- backend
ports:
- "5002:5002"
Dockerfile
FROM golang:1.8
RUN go get -u github.com/derekparker/delve/cmd/dlv
RUN dlv debug --listen=:2345 --headless --log ./cmd/main.go
command
docker-compose -f docker-compose.yml up --build --abort-on-container-exit
Result
2017/09/04 15:58:33 server.go:73: Using API v1 2017/09/04 15:58:33
debugger.go:97: launching process with args: [/go/src/debug] could not
launch process: fork/exec /go/src/debug: operation not permitted
The compose syntax is correct. But the security_opt will be applied to the new instance of the container and thus is not available at build time like you are trying to do with the Dockerfile RUN command.
The correct way should be :
Dockerfile:
FROM golang:1.8
RUN go get -u github.com/derekparker/delve/cmd/dlv
docker-compose.yml
networks:
backend:
services:
example:
build: .
security_opt:
- seccomp:unconfined
networks:
- backend
ports:
- "5002:5002"
entrypoint: ['/usr/local/bin/dlv', '--listen=: 2345', '--headless=true', '--api-version=2', 'exec', 'cmd/main.go']
