I am trying to run a symfony command through cron but it is now executing never. The application is runningin docker and I can't find information if I need to specify roles or something else. Other standard linux commands are executed successfully but looks like cron doesn't want to start app/console. Here is my cronjob:
* * * * * /usr/local/bin/php /usr/lib/myApp/app/console myCommand --env=prod >> /usr/lib/myApp/testLog.txt 2>&1
Does anyone have any suggestions how to run symfony command in docker using cron?
The philosophy of Docker is to have one process per container. That means, you usually have no init system and thus, no services running inside the container, e.g. dbus or cron.
There are ways to create your own Docker Image with such an init-system/background service. Images based on Alpine often use S6.
Another solution is to have use the cron-service on your host and rewrite the command to something like docker exec <container_name> /usr/local/bin/php ...

I'm using a wp-cli tool in order to optimize images:
$ wp image-optimize batch --limit=20
I've installed wpcli using composer so it's in an unusual location, but is in my $PATH:
/home/user/.config/composer/vendor/wp-cli/wp-cli/bin/wp
This works great. I'd like to run this command nightly. I've tried two different approaches to this. First, I tried running the command as a cronjob (set every minute for testing):
$ crontab -e
* * * * * cd /path/to/example.com && wp image-optimize batch --limit=20
I got no response. I wondered if the problem had something to do with passing arguments in a cronjob. So, I created a bash script nightly-image-optimize (also in path) hoping that this might get around it:
#!/bin/bash
echo "begin" >> /home/user/cronlog.log
cd /path/to/example.com
sh /home/user/.config/composer/vendor/wp-cli/wp-cli/bin/wp image-optimize batch --limit=2
echo "end" >> /home/user/cronlog.log
I then modified the cronjob to execute this file every minute as my username since cron runs as root:
* * * * * username /usr/local/bin/nightly-image-optimize
I know the cronjob is running because my cronlog.log file is created and is populated every minute with the echo begin and end statements above.
While in context this is a wp-cli problem, I don't believe that the issue has anything to do with wp-cli. I think I'm misunderstanding how to essentially 'tell' bash to run a process as if I had manually entered it in (maybe something to do with the interactivity of wp-cli?).
Any ideas?

I have a simple dokku app using herokuish buildpack-php with a procfile: web: vendor/bin/heroku-php-apache2 public/
If I try to enter the app with dokku enter <appname> nothing happens, and I am simply returned to my host shell.
I can run dokku run <appname> bash and get a shell, but is, as far as I understand from the documentation placing me in a new container and not in the existing/running one I need access to:
The run command can be used to run a one-off process for a specific command. This will start a new container and run the desired command within that container.
How can I fix this so I can enter my running container?
If you are in the local directory for your app, doing the following will take you into the running container for it:
dokku enter web.1
I've done this a few times today!
As a workaround, you can enter your container using docker. For doing so, run docker ps and note the container ID. Afterwards, run docker exec -it container_id /bin/bash.
I'm testing WordPress for personnal project but i would like to install locally my development WordPress website and install on my Personnal production server the final website.
In order to do that, i search a plugin or program for syncronising wordpress dévelopment with new pages, templates, and configurations inside my production wordpress.
Is there a program or plugin to do that? How is much better to work with wordpress?
Thanks :)
There are two topics you can try:
-.By schedule copy files to production like linux CLI with crontab (every min):
* * * * * scp local_file remote_username#remote_ip:remote_file
But I don't recommend this way , and for you to easy understand.
-.By CICD, here is a blog link for you to know the concept first if you don't know this:
https://thecodingmachine.io/continuous-delivery-on-a-dedicated-server
Briefly, you can push your project to private repo on gitlab or github,
then make development(=development server),production(=production server) branches, the automate job will deploy to the servers if you have git push.
Here's an example main part from the link on the file .gitlab-ci.yml:
deploy_staging:
stage: deploy
image: kroniak/ssh-client:3.6
script:
# add the server as a known host
- mkdir ~/.ssh
- echo "$SSH_KNOWN_HOSTS" >> ~/.ssh/known_hosts
- chmod 644 ~/.ssh/known_hosts
# add ssh key stored in SSH_PRIVATE_KEY variable to the agent store
- eval $(ssh-agent -s)
- ssh-add <(echo "$SSH_PRIVATE_KEY")
# log into Docker registry
- ssh deployer#thecodingmachine.io "docker login -u gitlab-ci-token -p $CI_BUILD_TOKEN registry.thecodingmachine.com"
# stop container, remove image.
- ssh deployer#thecodingmachine.io "docker stop thecodingmachine.io_${CI_COMMIT_REF_SLUG}" || true
- ssh deployer#thecodingmachine.io "docker rm thecodingmachine.io_${CI_COMMIT_REF_SLUG}" || true
- ssh deployer#thecodingmachine.io "docker rmi registry.thecodingmachine.com/tcm-projects/thecodingmachine.io:${CI_COMMIT_REF_SLUG}" || true
# start new container
- ssh deployer#thecodingmachine.io "docker run --name thecodingmachine.io_${CI_COMMIT_REF_SLUG} --network=web -d registry.thecodingmachine.com/tcm-projects/thecodingmachine.io:${CI_COMMIT_REF_SLUG}"
only:
- branches
except:
- master
It maybe hard for you to read this, but you can know there is a way which can work you need and you may take times to learn this part.
Hope it work for you.
Thanks for David Négrier sharing.
I need nginx-openresty and redis in single docker container. I have written docker file its working fine. But thing i need to start my redis service after login into the docker bash to automate this I have written .sh file which contains instrutions like start and stop of redis server and nginx. ENTRYPOINT ["./startup.sh"]
and .sh file is
cd /etc/redis-installation/utils
echo -n | ./install_server.sh
service redis_6379 stop
cd /
cp ./dump.rdb /var/lib/redis/6379/
service redis_6379 start
openresty
My problem is that docker container start and exist when shell execution completed. How can stay the container keep running with nginx and redis in running state.
Try using docker-compose with a link between your app container and your redis container. I suggest using the official redis container
I am developing a web application which depends on a moodle system, as it uses moodles webservices. For my automated tests, I wanted to use docker to provide a preconfigured moodle-application on all my machines. Therefore I created a docker image, which I import from a .tar.gz file.
However, creating a new container-instance from this image behaves inconsistently. Sometimes the container boots up correctly and everything works fine. However, sometimes the container starts but the moodle-website is not reachable. If I connect my bash to the container using docker exec -it <container> bash I see that apache is running. The error logs do not show any entries which might be related to this issue.
If I kill the container instance and boot it up again, everything works as expected (sometimes this step has to be repeated multiple times). Do you have any idea what could be the reason for this strange behaviour? Anyone experiencing similar issues?
Docker is running on Ubuntu 14:04. The problem appears on several machines. The script which imports the image and starts the container looks like this:
#!/usr/bin/env bash
docker rm -f moodle
docker load < my-moodle.tar.gz
docker run -d -p 8080:80 -p 8443:443 -p 3306:3306 --name moodle moodle-image
Thanks in advance!
Successful container startup depends on your container entrypoint and external resources (if the entrypoint has external dependencies). What is the entrypoint? Does it depend on external resources?
