I'm trying to create a simple script which would:
- Connect to docker container's BASH shell
- Go into redis-cli
- Perform a
flushall
command in redis-cli
So far, I have this in my docker_script.sh
(this basically copies the manual procedure):
docker exec -it redis /bin/bash
redis-cli
flushall
However, when I run it, it only connects to the container's BASH shell and doesn't do anything else. Then, if I type exit
into the container's BASH shell, it outputs this:
root@5ce358657ee4:/data# exit
exit
./docker_script.sh: line 2: redis-cli: command not found
./docker_script.sh: line 3: keys: command not found
Why is the command not found
if commands redis-cli
and flushall
exist and are working in the container when I perform the same procedure manually? How do I "automate" it by creating such a small BASH script?
Thank you

Seems like you're trying to run /bin/bash
inside the redis container, while the redis-cli
and flushall
commands are scheduled after in your current shell instance. Try passing in your redis-cli
command to bash like this:
docker exec -it redis /bin/bash -c "redis-cli FLUSHALL"
The -c
is used to tell bash to read a command from a string.
Excerpt from the man
page:
-c string If the -c option is present, then commands are read from
string. If there are arguments after the string, they
are assigned to the positional parameters, starting with
$0.
