I’ve just disabled CDN to save the cost. However, all the old images, which is uploaded while I was using cloudfront, are failed to load.
For example:
I have CDN URL is `cdn.mydomain.com`. After disabling CDN, the `cdn.mydomain.com` is invalid so that all the images should start with `mydomain.com` instead.
**Is there anyway to convert all those urls programmatically?**

Note: I am going to use S3 to store all my images. Can I just make use of this opportunity to convert everything from cdn to s3 url?

You will need to rebake all your post to update the urls. There are 2 ways of doing it:
The low-CPU usage but _slow_ way
```plaintext
# ssh into server
cd /var/discourse
./launcher enter app
rails c
Post.update_all(baked_version: nil)
```
The high-CPU usage but faster way
```plaintext
# ssh into server
cd /var/discourse
./launcher enter app
rake posts:rebake
```

I tried your post here
[https://meta.discourse.org/t/disabled-cdn-emoji-picture-url-error/20878/2?u=trandatnh](https://meta.discourse.org/t/disabled-cdn-emoji-picture-url-error/20878/2)
But I received this error:
```plaintext
rake posts:rebake
rake aborted!
No Rakefile found (looking for: rakefile, Rakefile, rakefile.rb, Rakefile.rb)
(See full trace by running task with --trace)
```
I think it is because the answer was very old.
I added `--trace`
```plaintext

You need to run that command from **inside** the container (via `./launcher enter app`)

I ran the command but I got this error
```plaintext
root@daynhauhoc:/var/discourse# ./launcher enter app
Error: Command not found: exec
Error: Command not found: -it

```
I am using `v1.4.0.beta1 +4`. I used to be able to `rake` last time when I migrated from S3 to local. I think docker is ~~up to date~~ outdated.
```plaintext
root@daynhauhoc:/var/discourse# git pull
Already up-to-date.
root@daynhauhoc:/var/discourse# ./launcher rebuild app

I’ve just temporary upgraded Digital Ocean droplet to higher plan using flexible resize feature because I think the rake will take a lot of CPU usage. ~~But I don’t think resizing the droplet causes any issue with docker.~~
I am using docker 1.2
```plaintext
root@daynhauhoc:/var/discourse# docker -v
Docker version 1.2.0, build fa7b24f
```
Upgraded to 1.6
```plaintext
apt-get install lxc-docker
root@daynhauhoc:/var# docker -v
Docker version 1.6.2, build 7c8fca2
```

**Update 1** Successfully enter app and raking
```plaintext

**Update 2** All the images are OK now. Thank @zogstrip 👍
