I deleted a docker-compose without pushing it to git...I know I'm an idiot. The stack is still up so is there anyway to recreate that docker-compose ? I can do a docker inspect and see all the bits I need i.e. volumes used, variables etc but if there's some trickery to get that compose back with minimal effort that would be great.
Thanks,
First, you will need to get the equivalent docker run command, you can use this tool to do it: https://github.com/nexdrew/rekcod.
After you have the docker run command, you can use this other tool to convert it to a docker-compose file: https://composerize.com/.
E.g.:
I have the following docker-compose file:
version: '2'
services:
logstash:
image: docker.elastic.co/logstash/logstash:5.6.3
ports:
- 9600:9600
volumes:
- ./pipeline/logstash.conf:/usr/share/logstash/pipeline/logstash.conf
- ./config/:/usr/share/logstash/config
I run docker-compose up and end up with the following container:
$ docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
5febb7edb627 docker.elastic.co/logstash/logstash:5.6.3 "/usr/local/bin/dock…" 2 minutes ago Up 2 minutes 5044/tcp, 0.0.0.0:9600->9600/tcp logstash563_logstash_1
Then, I generate the docker run equivalent command for the underlying container:
$ rekcod 5febb7edb627
docker run --name logstash563_logstash_1 -v /workplace/mariodes/docker/logstash/logstash-5.6.3/pipeline/logstash.conf:/usr/share/logstash/pipeline/logstash.conf:rw -v /workplace/mariodes/docker/logstash/logstash-5.6.3/config:/usr/share/logstash/config:rw -p 9600:9600/tcp --net logstash563_default --restart no -h 2392ddc1cea7 --expose 5044/tcp --expose 9600/tcp -e 'PATH=/usr/share/logstash/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin' -e 'ELASTIC_CONTAINER=true' -e 'LANG=en_US.UTF-8' -e 'LC_ALL=en_US.UTF-8' -d --entrypoint "/usr/local/bin/docker-entrypoint" docker.elastic.co/logstash/logstash:5.6.3
Now, copy the output from rekcod and use it on https://composerize.com/ to convert it to a docker-compose file:
version: 3
services:
logstash:
container_name: logstash563_logstash_1
volumes:
- '/workplace/mariodes/docker/logstash/logstash-5.6.3/pipeline/logstash.conf:/usr/share/logstash/pipeline/logstash.conf:rw'
- '/workplace/mariodes/docker/logstash/logstash-5.6.3/config:/usr/share/logstash/config:rw'
ports:
- '9600:9600/tcp'
restart: no
expose:
- 5044/tcp
- 9600/tcp
environment:
- 'PATH=/usr/share/logstash/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin'
- ELASTIC_CONTAINER=true
- LANG=en_US.UTF-8
- LC_ALL=en_US.UTF-8
entrypoint:
- /usr/local/bin/docker-entrypoint
image: 'docker.elastic.co/logstash/logstash:5.6.3'
