How to remove discourse website

Product Support Self-hosting

AI-generated summary

A user, eminov, wants to uninstall their Discourse website. pfaffman suggests using rm -r /var/discourse to delete Discourse and all backups. However, this does not completely remove Docker and Discourse from the system.

To completely remove Docker, pfaffman recommends using apt-get purge docker-engine and then rebooting. BattleMage provides a step-by-step guide to remove Discourse:

  1. List local Docker images: docker images
  2. Remove the Discourse image: docker image rm discourse/discourse:1.3.10
  3. Remove the location where Discourse was cloned: rm -r /var/discourse

Additionally, pfaffman notes that before removing the image, you need to stop the Discourse container using docker stop app or . /launcher stop app.

BobbyZopfan asks about the relationship between Docker and the underlying Ubuntu Server OS. marianord explains that Docker is an application installed in the OS, and Discourse runs on top of Docker.

Finally, Bathinda asks how to completely remove all Discourse settings, users, and posts. pfaffman recommends removing the /var/discourse/shared folder using rm -rf /var/discourse/shared and then rebuilding Discourse.

This CMS is a very good, but a lot of things modified. As difficult installation, modification, and so the addition of a plugin and etc.

I want uninstall my discourse website? Which command do I have to write for that?

2

I’m not sure what you are asking? Are you looking to wipe the content of the forum?

3

rm -r /var/discourse

Will delete Discourse and all backups and everything. I’m not clear why not just shut down the droplet, though.

4

After
rm -r /var/discourse

site down.

I want remove delete discourse cms from my website. How delete docker and discourse?

Edit: I just checked, and if you installed Docker with the http://get.docker.com’s script and are running Ubuntu,

apt-get purge docker-engine

should remove docker. You’ll probably need to reboot to make sure all docker processes get killed.

In short: whatever you did to get Discourse running, do the reverse of that.

If you want to completely remove discourse:

  1. List you local docker images from the host: docker images
  2. Find the discourse image. It should look something like
    REPOSITORY            TAG                 IMAGE ID            CREATED             SIZE
discourse/discourse   1.3.10              95332d4db04b        5 weeks ago         1.52GB
  3. Remove the image: docker image rm discourse/discourse:1.3.10. Remember to use the exact same name and version your docker output showed you.
  4. Remove the location you cloned the discourse. If you followed the installation instructions, it should be /var/discourse, so rm -r /var/discourse should do it.
  5. [optional]. If you don’t need docker anymore, remove it from your machine.

Comandos muito bons. Eu também estava me perguntando sobre eles.

2 pequenas coisas:
Recebi a mensagem "Unable to remove repository reference “image name” (must force) container iccfa6e6d14b is using its referenced image 654a4f02e531.

  1. Como podemos impedir que a imagem seja usada? Se desligarmos o droplet, o console nĂŁo funcionarĂĄ.

  2. O Docker Ă© algo separado do sistema operacional Ubuntu Server subjacente?

Obrigado.

Se vocĂȘ destruir o droplet, o Discourse serĂĄ removido junto, entĂŁo nada disso importa, mas


Acho que vocĂȘ precisa executar

docker stop app

Ou

. /launcher stop app

Antes de poder remover a imagem.

Obrigado novamente.
Mas eu gostaria que vocĂȘ tambĂ©m respondesse Ă  minha 2ÂȘ pergunta, que acredito que deve ser uma resposta de quase uma linha.

Pesquisei no Google por essa resposta por cerca de 1 hora.
E li toda essa discussĂŁo sobre o tĂłpico no meta, aqui.

Mas nĂŁo consegui entender.
Posso repetir meu dilema:
SerĂĄ que Ă© assim:
Existe o sistema operacional Ubuntu e, em seguida, uma instalação normal do Docker nele/ sobre ele.
E nessa instalação do Docker, o Discourse Docker estå rodando?
Ou Ă© simplesmente o Ubuntu Server OS com o Discourse Docker instalado/rodando nele?
Ou nĂŁo Ă© chamado de ‘Discourse Docker’, mas sim algo diferente?

P.S: TambĂ©m tentei entender a mesma coisa atravĂ©s deste longo tĂłpico. Mas ele apenas nĂŁo conseguiu responder Ă  minha dĂșvida (quase conseguiu, mas nĂŁo exatamente).

11

Sim. VocĂȘ tem o Ubuntu como sistema operacional, depois o Docker como um aplicativo instalado no sistema operacional, e o Discourse rodando sobre o Docker.

O Docker cria a possibilidade de isolar aplicativos em contĂȘineres (vamos simplificar como uma MĂĄquina Virtual leve), onde vocĂȘ pode executar mĂșltiplos aplicativos sem atrapalhar o sistema operacional.

12

Eu removi o contĂȘiner de dados do Docker (e talvez o web_only tambĂ©m), mas, ao reinstalar/recriar o contĂȘiner de dados, os mesmos administradores/usuĂĄrios (e configuraçÔes) aparecem novamente.

Eu queria começar do zero para instalar o Discourse novamente. É realmente necessário desinstalar o Docker para isso? Ou devo remover toda a pasta /var/discourse?

Não existe alguma pasta ou local específico que armazene todos os dados do Discourse, de modo que sua remoção eliminasse todas as configuraçÔes, usuårios, administradores e posts?

Obrigado.

rm -rf /var/discourse/shared

Em seguida, reconstrua. É lá que os volumes persistentes são armazenados por padrão.
