File won't copy to Docker file? - bash

I run this file (partial) under "root" account on my Synology.
but it won't start, in my error log I got this message:
[FATAL tini (9)] exec /home/qgis/cmd.sh failed: No such file or directory
Can someone help me please...
This is the part where cmd.sh is added:
ENV TINI_VERSION v0.19.0
ADD https://github.com/krallin/tini/releases/download/${TINI_VERSION}/tini /tini
RUN chmod +x /tini
ENV QGIS_PREFIX_PATH /usr
ENV QGIS_SERVER_LOG_STDERR 1
ENV QGIS_SERVER_LOG_LEVEL 2
COPY cmd.sh /home/qgis/cmd.sh
RUN chmod -R 777 /home/qgis/cmd.sh
RUN chown qgis:qgis /home/qgis/cmd.sh
USER qgis
WORKDIR /home/qgis
ENTRYPOINT ["/tini", "--"]
CMD ["/home/qgis/cmd.sh"]
create a file cmd.sh with this content:
This is the cmd.sh file:
#!/bin/bash
[[ $DEBUG == "1" ]] && env
exec /usr/bin/xvfb-run --auto-servernum --server-num=1 /usr/bin/spawn-fcgi -p 5555 -n -d /home/qgis -- /usr/lib/cgi-bin/qgis_mapserv.fcgi

Docker container unable to ignore the EntryPoint bash script failure

Bash script:
clonePath=/data/config/
git branch -r | fgrep -v 'origin/HEAD' | sed 's| origin/|git checkout |' > checkoutAllBranches.sh
chmod +x checkoutAllBranches.sh
echo "Fetch branch: `cat checkoutAllBranches.sh`"
./checkoutAllBranches.sh
git checkout master
git remote rm origin
rm checkoutAllBranches.sh
for config_dir in `ls -a`; do
cp -r $config_dir $clonePath/;
done
echo "API Config update complete..."
Dockerfile which issues this script execution
ENTRYPOINT ["sh","config-update-force.sh","|| true"]
The error below causes the container startup failure despite setting the command status to 0 manually using || true
ERROR:
Error:
cp: cannot create regular file '/data/./.git/objects/pack/pack-27a9d...fb5e368e4cf.pack': Permission denied
cp: cannot create regular file '/data/./.git/objects/pack/pack-27a9d...fbae25e368e4cf.idx': Permission denied
I am looking for 2 options here:
Change these file permissions and then store them in the remote with rwx permissions
Do something to the docker file to ignore this script failure error and start the container.

When you do in the script...
chmod +x checkoutAllBranches.sh
...than why not before cp
chmod -R +rwx ${clonePath}
...or if the stderr message 'wont impact anything'...
cp -r $config_dir $clonePath/ 2>/dev/null;
...even cp dont copy -verbosly.

When your Dockerfile declares an ENTRYPOINT, that command is the only thing the container does. If it also declares a CMD, the CMD is passed as additional arguments to the ENTRYPOINT; it is not run on its own unless the ENTRYPOINT makes sure to execute it.
Shell errors are not normally fatal, and especially if you explicitly set +e, even if a shell command fails the shell script will keep running. You see this in your output where you get multiple cp errors; the first error does not terminate the script.
You need to do two things here. The first is to set the ENTRYPOINT to actually run the CMD; the simplest and most common way to do this is to end the script with
exec "$#"
The second is to remove the || true from the Dockerfile. As you have it written out currently, this is passed as the first argument to the entrypoint wrapper – it is not run through a shell and it is not interpreted as a "or" operator. If your script begins with a "shebang" line and is marked executable (both of these are correct in the question) the you do not explicitly need the sh interpreter.
# must be a JSON array; no additional "|| true" argument; no sh -c wrapper
ENTRYPOINT ["./config-update-force.sh"]
# any valid CMD will work with `exec "$#"
CMD java $BASE_JAVA_OPTS $JAVA_OPTS -jar my-api-config-server.jar

Why does my bash script not run properly on every docker container that starts up?

My Dockerfile copies an init.sh script to the container.
# DOCKERFILE
FROM ubuntu:latest
# a bunch of installation commands
COPY init.sh /
ENTRYPOINT bash init.sh
EXPOSE 80
And I have a docker-compose file with 2 services:
Service1: This service is being scaled.
Service2: Database
I have it so that when the Service1 container starts up, this script will run.
#!/bin/bash
# script
# Missing files directory
if [[ ! -e /var/www/drupal/sites/default/files ]]; then
mkdir /var/www/drupal/sites/default/files
chmod a+w /var/www/drupal/sites/default/files
fi
# Missing settings file
cp /var/www/drupal/sites/default/default.settings.php /var/www/drupal/sites/default/settings.php
chmod a+w /var/www/drupal/sites/default/settings.php
# Install Drush & Install Drupal
cd /var/www/drupal && composer require --dev drush/drush
cd /var/www/drupal && vendor/bin/drush site-install standard \
--db-url=mysql://root:random#mariadb:3306/drupaldb -y \
--site-name=ExampleWebsite \
--account-name=random \
--account-pass=random
# Post-Installation Steps
chmod go-w /var/www/drupal/sites/default/settings.php
chmod go-w /var/www/drupal/sites/default
cd /var/www/drupal && vendor/bin/drush cache-rebuild
/usr/sbin/apache2ctl -D FOREGROUND
However, when I run the command to start up the containers along with --scale docker-compose up -d --scale Service1=5, some of the containers run the script properly on start up but some don't. For the ones that don't, I would have to go into the container and manually run the script, then it's fine.
Shouldn't all the containers be the same and would've run the same script properly?
Instead, I would have to manually go into some of the containers and run the script.

docker-compose up permission denied on sh file

I have the following docker-compose.yml file:
version: "3" services:\ local_db:
build:
context: mssql-data
dockerfile: Dockerfile
ports:
- "1433:1433"
volumes:
- ~/Documents/rfg/temp
environment:
SA_PASSWORD: "D0ckerDev"
ACCEPT_EULA: "Y"
When I run docker-compose up I get the following error:
local_db_1 | /scripts/entrypoint.sh: line 5: /scripts/seed-data.sh: Permission denied
docker_local_db_1 exited with code 126
Where entry point is:
#start SQL Server in the background
/opt/mssql/bin/sqlservr &
# start the seed data script
/scripts/seed-data.sh
Where seed-data.sh was:
sleep 15s cd /scripts
if [ -f /var/opt/mssql/data/initialized ]; then
sleep infinity
fi sleep 15s /opt/mssql-tools/bin/sqlcmd -S localhost -U sa -P $SA_PASSWORD -d master -i setup.sql
touch /var/opt/mssql/data/initialized sleep infinity
and entrypoint.sh:
#start SQL Server in the background
/opt/mssql/bin/sqlservr &
# start the seed data script
/scripts/seed-data.sh
and the Dockerfile:
FROM microsoft/mssql-server-linux:2017-latest
COPY . /scripts
CMD chmod 755 /scripts/*
CMD chmod 755 /scripts/seed-data.sh
CMD /bin/bash /scripts/entrypoint.sh
The above works fine in Windows but on MacOS I get th epermission denied error above..
It looks like you haven't set the correct permissions on your seed-data.sh script. You could just call it like this:
sh /scripts/seed-data.sh
Or you can make sure all your scripts are executable first:
chmod 755 /scripts/*
/scripts/seed-data.sh

Dockerfile commands not executing in MacOS

I am trying to build a container using docker file which has some statements to execute as below:
# Create folder for caching files
RUN mkdir -p /Library/WebServer/docroot/publish
RUN chown -R daemon:daemon /Library/WebServer/docroot
I am using below command to build :
$ docker build --no-cache -t dispatcher-apache -f Dockerfile
I can see the below execution :
Step 7/10 : RUN mkdir -p /Library/WebServer/docroot/publish
---> Running in 4c8f7c3e2238
But the file isn't created on that location when I check.
-bash: cd: /Library/WebServer/docroot/publish: No such file or directory
However, if I create commands from terminal, it works fine.
Dockerfile :
FROM httpd:2.4
# Copy dispatcher module
RUN mkdir -p /private/libexec/apache2/
COPY ./apache2-modules/ /private/libexec/apache2/
RUN ln -s /private/libexec/apache2/dispatcher-apache2.4-4.2.3.so /private/libexec/apache2/mod_dispatcher.so
# Copy new apache dependencies
RUN mkdir -p /private/etc/apache2/conf
COPY ./publish/etc/httpd/conf.d/ /private/etc/apache2/conf/
# Create folder for caching files
RUN mkdir -p /Library/WebServer/docroot/publish
RUN chown -R daemon:daemon /Library/WebServer/docroot
# Create folder for log files
RUN mkdir -p /private/var/log/apache2
# Replace httpd.conf with enabled modules
COPY ./my-httpd.conf /usr/local/apache2/conf/httpd.conf
EDIT after some help:
Now after build, I started the container and below is the error
$ docker run -dit -e HOSTIP=$(ipconfig getifaddr en0) --rm --name dispatcher-app -p 8080:80 dispatcher-apache
6a032a50be846bef06027976b990da27bcb446c28d582cf6c3a4dc4ad4361e1c
$ docker exec -it dispatcher-app /bin/bash
Error: No such container: dispatcher-app
Any troubleshooting tips?

Dockerfile CMD not running at container start

So i've written a Dockerfile for a project, i've defined a CMD to run on starting the container to bootstrap the application.
The Dockerfile looks like
# create our mount folders and volumes
ENV MOUNTED_VOLUME_DIR=sites
RUN mkdir /$MOUNTED_VOLUME_DIR
ENV PATH=$MOUNTED_VOLUME_DIR/sbin:$MOUNTED_VOLUME_DIR/common/bin:$PATH
RUN chown -Rf www-data:www-data /$MOUNTED_VOLUME_DIR
# Mount folders
VOLUME ["/$MOUNTED_VOLUME_DIR/"]
# Expose Ports
EXPOSE 443
# add our environment variables to the server
ADD ./env /env
# Add entry point script
ADD ./start.sh /usr/bin/startContainer
RUN chmod 755 /usr/bin/startContainer
# define entrypoint command
CMD ["/bin/bash", "/usr/bin/startContainer"]
The start.sh script, does some git stuff like cloning the right repo, setting environment vars, as well as starting supervisor.
The start script begins with this
#!/bin/bash
now=$(date +"%T")
echo "Container Start Time : $now" >> /tmp/start.txt
/usr/bin/supervisord -n -c /etc/supervisord.conf
I start my new container like this
docker run -d -p expoPort:contPort -t -i -v /$MOUNTED_VOLUME_DIR/$PROJECT:/$MOUNTED_VOLUME_DIR $CONTAINER_ID /bin/bash
when i login to the container i see that supervisor hasn't been started, and neither has nginx or php5-fpm. the /tmp/start.txt file with a timestamp set from the startContainer script doesn't exist, showing its never ran the CMD in the Dockerfile.
Any hints on to get this fixed would be great
This:
docker run -d -p expoPort:contPort -t -i -v /$MOUNTED_VOLUME_DIR/$PROJECT:/$MOUNTED_VOLUME_DIR $CONTAINER_ID /bin/bash
Says 'run /bin/bash' after instantiating the container. E.g. skip CMD.
Try this:
docker run -d -p expoPort:contPort -t -i -v /$MOUNTED_VOLUME_DIR/$PROJECT:/$MOUNTED_VOLUME_DIR $CONTAINER_ID
